  1. Why Your Bra Size Feels Wrong: Bra Fit, Shapes & Easy Fixes

    Posted on

    Bra Sizing Without the Tears

    Why your “right bra size” can still feel wrong (and what to try instead)

    If bras have ever made you feel like you’re the problem — you’re not. Bra sizing is a starting point, not a promise. Two bras with the same bra size on the label can fit completely differently, and it’s usually down to bra shape and bra style, not anything about you.

    I’ve got separate bra sizing guides for cis and trans customers if you want the step-by-step measuring side. But this post is about the part nobody explains properly:

    why your bra fit can feel “wrong” even when the size should be right — and what that usually means.


    Why bras aren’t universal (even when the size matches)

    A bra size gives you a rough idea of band size and cup size (and cup volume), but it doesn’t tell you:

    • where your fullness sits (top, bottom, centre, wider-set)

    • whether you’re more shallow or more projected (how far forward volume sits)

    • how tall the cups are, how wide the wires are, or how stretchy the band is

    • how the bra is constructed (moulded, seamed, padded, unlined)

    So when something feels off, it often means the bra style isn’t matched to your shape or your comfort goals — not that you’ve “failed” at bra sizing.


    Bra shapes that change everything (and why)

    Think of these as different “cuts,” like jeans. Same size on the label, wildly different results.

    T-shirt bra (moulded cup bra)
    Smooth under clothes, but the cup is pre-shaped and doesn’t adapt much. If you don’t match the mould, you can get gaping or spillage even in the “right” cup size.

    Balconette bra
    More open at the top, lifts from underneath. Often great for a rounded look, but can cut in if you’re fuller on top.

    Plunge bra
    Lower centre gore (the bit between the cups) and a deeper neckline. Often brilliant for cleavage and also helpful if a high centre feels uncomfortable.

    Full cup bra
    More coverage and a “contained” feel. Can be very secure, but sometimes gapes if the cups are tall and you’re not full at the top.

    Unlined bra / seamed cup bra
    More flexible and often more forgiving because the fabric shapes to you instead of expecting you to match a fixed shape. A great “reset” option if bra fitting has started to feel like guesswork.


    “Why does this bra feel wrong?” The most common reasons

    1) Gaping at the top of the cups

    Often a bra shape mismatch: the cups are too tall, too stiff (hello, moulded T-shirt bra), or the straps sit too wide and pull the cup oddly.
    Try: a plunge bra, balconette bra, or an unlined bra before assuming you need a smaller cup.

    2) Spilling over the top or sides

    This can be cup volume, but it can also be a cup that’s too closed on top or too narrow for your shape.
    Try: a more open cup style, or one cup size up in the same style (brands vary a lot here).

    3) Band rides up at the back

    Usually the band size is too loose (or the band fabric is very stretchy), so everything shifts and the straps end up doing the heavy lifting.
    Try: a firmer band, or a style with more supportive band construction.

    4) Underwire feels stabby or sits on tissue

    That’s often underwire shape, not “you picked the wrong size.” Wires vary hugely in width and height, especially at the centre.
    Try: a different bra style (often a plunge bra helps if the centre feels pokey), or a different brand whose wires suit you better.

    5) Straps dig in

    Often the band isn’t providing enough support, so straps try to do the band’s job.
    Try: prioritising a secure band fit first, then adjusting straps.


    A quick note for trans customers

    A lot of standard bra fitting advice is written as if everyone’s body is built the same way. In reality, ribcage shape, spacing, and where volume sits can change which bra styles feel best — and that’s why one person’s perfect T-shirt bra is another person’s gaping nightmare.

    Comfort and confidence are the goal. The label is just a clue.


    The kinder way to bra shop

    Instead of “What’s wrong with me?” try:

    “What is this bra designed to do — and does that match my shape and my comfort goals?”

    If you want the step-by-step measuring side, my bra sizing guides (cis and trans) are there. But if you’re stuck in the loop of “my bra size should fit and it doesn’t”… it’s usually the bra style that needs changing — not you.

  2. Bra Inserts, Chicken Fillets and Breast Forms: What’s the Difference?

    Posted on

    Breast form bra insert choice

    What’s the Difference Between Bra Inserts and Breast Forms?

    If you’ve ever searched for bra inserts, breast enhancers, breast forms, or even the old nickname chicken fillets, you’ve probably noticed the internet muddles them all together. They might sit next to each other on search pages, but they’re actually designed for very different things.

    Here’s a simple, friendly guide to what each one does and how you might choose between them.


    Bra Inserts (Breast Enhancers)

    These are the pieces that work with your natural breast to change shape, balance, or projection. They come in a huge range of sizes and styles — far wider than the classic chicken fillets most people remember. Some are small and subtle; others are much fuller, offering lift, projection, or a more defined curve. In my own range, I’ve expanded way beyond the old “one shape fits all” approach so there’s something for many different bodies and goals.

    People use bra inserts when they want to:

    • balance natural asymmetry (including Poland syndrome or differences after a lumpectomy)

    • fill gaping or soft areas in a bra

    • support softer breast tissue after breastfeeding or age-related changes

    • add lift, projection, or cleavage

    • get a discreet boost for daily wear

    • shape their silhouette during a trans journey
      (from very subtle dressing without anyone knowing, through to enhancing early growth or helping create natural cleavage)

    Because breast tissue density varies so much, the same insert can look completely different on two people. Softer breasts tend to “absorb” silicone more, so some people need a bit more oomph to get the look they want, while others get lift easily from a lighter piece. That’s why having many shapes and weights matters — it makes it easier to find something that genuinely works for your body rather than forcing your body to fit a single shape.


    Breast Forms

    Breast forms, on the other hand, are designed to replace or create the entire breast shape. They usually have a full outer curve, a contoured back, and a realistic nipple, and they don’t depend on your natural breast tissue at all.

    People use breast forms when they want to:

    • create a full breast shape on a flat or reduced chest

    • achieve a realistic silhouette after surgery

    • express a feminine look during cross-dressing or transition

    • wear a complete curve that doesn’t rely on breast tissue for shape

    They’re ideal when someone needs an entire breast, not just more shape to the one they already have.


    Which one do you choose?

    Here’s the easiest way to look at it:

    Choose bra inserts / enhancers if you want to:

    • shape, balance, lift, or project your natural breast

    • create or enhance cleavage

    • fill a bra cup

    • stay subtle and discreet

    • support softer breast tissue

    • match existing breast tissue (e.g., after lumpectomy or natural asymmetry)

    • work with breast growth or expression on a trans journey

    Choose breast forms if you want to:

    • create a full breast from scratch

    • wear a realistic shape with a built-in nipple

    • present a feminine silhouette without relying on your natural breast

    • dress confidently after surgery or on a flat chest


    Why they’re often confused

    The term chicken fillets used to cover nearly everything — those little curved pads we all remember from years ago. But enhancers have moved on so much since then, with a huge range of shapes, textures, and effects. When some enhancers get large and structured, they can look a bit like mini breast forms, which is where the lines start to blur.

    But the real difference is simple:

    • Bra inserts enhance the breast you have.

    • Breast forms create the breast shape you want.

    Two different tools, both valid, both useful — just designed for different bodies, needs, and stories.

     

    Hopefully that helps, but I'm always here if you have any questions.

  3. Wedding Dress Bra Inserts & Breast Enhancers – Feel Confident on Your Big Day

    Posted on

    Bride wearing a strapless wedding dress with discreet bra inserts for added shape and support on her big day.

    Wedding Dress Ready: The Secret Helpers Under Your Gown

    Finding the dress is a huge moment — whether it’s for your wedding day, a civil ceremony, or another celebration of love. But once you’ve found the perfect dress, it’s completely normal to want a little extra support or shape underneath. That’s where my range of breast enhancers and bra inserts comes in.

    Over the years, I’ve helped countless brides (and bridesmaids!) feel more confident and comfortable in their dresses — especially when dealing with low necklines, tricky strapless styles, or just needing a better balance or silhouette. My enhancers are designed to lift, boost, or shape depending on what you need — without compromising comfort or elegance.

    Why My Bra Inserts Are Ideal for Bridalwear

    • Invisible under dresses: No visible edges or harsh shapes, just a smooth, natural curve. Most styles sit inside your bra, but some can be taped directly to the skin or your dress using my Boobylicious Tape.

    • Customisable options: With 12 different styles to choose from, there’s something for every cup size, dress style, and body shape. Whether you’re after a subtle lift or full-on wow factor, you’ll find a match.

    • Great for non-standard sizing: If your bust is asymmetrical or your body doesn’t fit mainstream sizing, I’ve got you covered — literally. These are for real people with real bodies.

    Wedding Dresses Don’t Always Work with Bras

    One of the most common issues I hear from brides is that their dress doesn’t work with a standard bra — whether that’s because it’s strapless, has an open back, or the fabric is too fine. This can leave you with less support than you’d like, and often a bit of a gap between your bust and the dress.

    Because wedding dresses are usually structured to skim rather than cling, it’s often necessary to go up a size in enhancer or insert to fill the space and get the lift or cleavage you want. This is totally normal — especially if the dress doesn’t compress the bust or has built-in padding that needs balancing.

    In some cases, the seamstress may have done all the alterations possible, but there’s still a visible gap at the bust. Or the dress simply won’t allow for any more adjustment. That’s when going even bigger with the enhancer can help bridge that gap and give the illusion of a perfect fit. If that’s you — don’t worry. Just get in touch and I’ll help you find the right solution.

    Not Sure What You Need? I Can Help.

    Weddings are stressful enough without worrying about what’s going on under your dress. So, if you're not sure which style is best, I’m always happy to help. Just pop me a message with a few details about your dress and what you’re hoping to achieve, and I’ll point you to the best options.

    You can also order with peace of mind — discreet packaging, fast delivery, and a return policy that gives you time to try your enhancers or bra inserts out before the big day.

    Top Picks for Brides

    All of these can be paired with Boobylicious Tape for extra security, especially useful in strapless or sheer dresses.


    Whatever your style, shape or gender identity — you deserve to feel your most confident self on your wedding day. And I’m here to help make that happen, with a little silicone magic and a lot of care.

    “Confidence isn’t about being perfect — it’s about feeling ready for the moments that matter.”

  4. Why Don't You Show the Enhancer in a Bra, Jo?

    Posted on

    When people make a purchase from my store, I send a little feedback email so people can let me know how they feel and how I can improve. 

    One thing that has been mentioned a few times is this: 

     

    "You really should include pictures of the enhancers on a someone so we can see the results" 

     

    I felt it's about time I responded to tell you I hear you! I need to explain my reasons for why I've not done that on my site.  

    It's something I explained a lot when I first started out (2007!) but not something I have chatted about recently, so I certainly feel it's time.  

    First of all, I fully understand the logic. We like to see a product in action in order to understand it.  I certainly do when I am buying things, like the jeans I am looking at getting myself at the moment. I like to see what size and height the model is, and work out roughly how they will work on me, based on that image. The problem is that enhancers don't quite work like that, and to put it simply, I don't want to mislead anyone. 

     

    Let me explain. 

    The problem we have is that what an enhancer looks like for one person, is not necessarily what it will look like for others.  I think this is a big issue as it can mislead. 

    There are a few factors involved in this.  The first is that if I show say a style 6 enhancer in a 34B bra, the result will look different to the look and boost that a it would if I photographed a 36C person with the exact same style.  As a result, I would be showing a product giving a result that will not happen, and that wouldn’t be right.  I could of course show images of the product in each bra size, but that would be about 30-60 pictures for each product. 

    Then it's compounded by the second factor, breast shape. 

    There are many different breast shapes out there, which all respond differently. This is in bras, but even more so with breast enhancers, especially when breast density is varies. They can be full on top, full on bottom, rounded, triangular, tubular etc.  

    To add to it, breasts can come in different densities and change over time, through age, breast feeding and weight loss. This really affects how much silicone we need, as breasts that are not so dense need more to push and shape. Someone with style 6 who hasn't breastfed may get a different amount of boost to someone who has.  

    Then it's the simple factor of the bra it's in. As I'm sure you know, bras are not equal, and all fit and work differently, from brands to different bra shapes.  The bra used in the image would not match the bra the customer uses.  

    With all those factors, you can see how if I put a model in a 34C bra with style 6, they could give a different visual image than the customer may get, even if they were a 34C. It's not something I feel comfortable about doing.  

    I did wonder about having the images labelled, so like the jeans say the model is this and that, for sizing reference, but at the end of the day there are so many factors that would mean the customer would get a different result. A jeans company only has to take a picture of say 10 sizes, and can show it for each, so it's quite accurate. My customers would vary so widely that it still wouldn't narrow it enough.  

    It's something that I hope to work around more in the future. I am a little store and I don't have the resources to do that now, and that's not really a bad thing. By keeping small I can't have all those images taken and sizing options expressed, but that does mean that it's just me running my shop, so I am here for you.  I like to keep it small and personal with you. 

    The main thing to remember is if you are not sure, use me! I try to give as much information as I can, but many of you have specific needs so use me as that's what I'm here for.  I have about 15 years of experience now, so pick my brains and we can work out it together. Tell me your size, goals, issues and we can go from there with finding you the perfect fitting breast enhancer ðŸ˜Š

  5. Finally :) Digital 400g Breast Form Comparison Image

    Posted on

    Here is it, my first digital comparison drawing of the 400g breast forms in full glorious colours! 

    I will tidy it all up with finer lines and one day and make it much prettier looking, but for now it fulfills the purpose and shows you a fabulous comparison of the shapes and sizes. You can print the PDF out in what should be accurate sizing, and I hope it will really help you.  Just make sure your printer is set to print at 100% size. 

    I started with the 300g and somehow moved on to the 400g before finishing, so I'll head back and finish that one next. Replicating the different sizes for each should be much quicker now that I've got the shapes digitised :)

    This new PDF will be added to all the 400g breast form pages and help pages.

  6. Breast Form Sizing 400g Sketch

    Posted on

    To follow on from my last post, here is the quick sketch for the 400g breast forms. 

    Comparision 400g forms

    Sorry it's not so neat! Instead of re-drawing it for you, I spent the time researching and ordering a graphics tablet.  Hopefully, I will be able to recreate it really well for you digitally that way.  I'm quite arty, so I am looking forward to using it to make you more resources to help.

    It may take me a while to get the hang of using it, but thanks to a lovely customer who replied to my previous post, I now have QCAD, which is software to help with making technical drawings. Fingers crossed! 

    You can however see from this sketch that there are only subtle differences at the top between style 1 (in green) and 2 (in purple), that the triangle shape is a balance between width and height (she manages more width due to her concave back meaning there is more silicone to spread out wider) and that the pear shape in red is a much bigger flatter style, so great for bigger body frames looking for a more subtle look. 

    If you have any questions, do let me know.

  7. New Breast Form Sizing Help

    Posted on

    Lightbulb

    I was chatting to a customer yesterday, and I suggested that they drew out the breast form they are interested in on a piece of paper, following the images on the site to help with the shape.

    I then sat down in the evening and thought, why haven't I done that for you?! 

    With the breast forms, they have the advantage of all going up in the same size increments and can therefore be directly compared. The only difference is the shape and how that is distributed. 

    Some a wider and flatter, and some are narrow and deeper/perkier. 

    It would surely be great for you if you had a visual guide for that, and especially if there was a printout you could do for each size if you wish. That way you can print it out and compare with your bras/the forms you already have/your body shape to see what would work best for you.

    I've had a try and I can draw them out well, one on top of each other in different colours to show you which style is which.  It's not the swishest and most sophisticated way of rendering it, but I'm sure it will really help until I can work out a better graphics way to do it for you.

    The only challenge I can see is ensuring that if you print it, it's replicated exactly in the right size.

    Here is my first try and draft.

    300g Styles Comparison

    Teardrop Style 2 is in the purple (small and pert)

    The Triangle is in the orange (wider, concave back and a mid-shaped style)

    Teardrop Style 1 is in the green (taller and pert)

    The Pear Shape is in the red, and is the biggest style, but with the least depth so the most subtle style.

     

    I think it will be really helpful for some, so I will get to drawing and scanning these as best I can, and then making them available to see and download.  

    If anyone has graphics ideas and knowledge about how I can do this best, please do get in touch :)

  8. Breast Enhancer Options for Small Breasts (and how bra size changes everything)

    Posted on

    Breast Enhancer Options for Small Breasts

    Breast Enhancers For Small Breasts

    Breast Enhancer Options for Small Breasts (and why bra fit matters so much)

    Having small breasts can be a blessing and a curse. I should know — I’m a 32B at the moment (but that can fluctuate). I love that I can sometimes go without a bra, but it can make fitting into certain tops and dresses a bit tricky.

    I don’t have time to blog nearly as much as I’d like, but I thought I really should write a quick guide for small breasts, because the more information you have, the easier it is to choose a style that actually works. I want you to feel confident picking what you need — and I’m here if you’d like help, of course.

    First: sizing isn’t science

    We’re all different, with different breast shapes, and what works beautifully for one person might not for another.

    Also, band size matters more than people realise. A 30A is not comparable to a 40A, for example — as band size goes up, the “A” cup physically holds more volume, so the space inside the bra cup is completely different.

    So with that in mind, let’s look at options.


    Bra Inserts for Small Breasts - If you have a small band and small cup

    If you have a small band and cup size, there’s simply less room inside the bra cup for us to work with.

    If you want to stay the same cup size

    If you want to stay in the same cup size, you’ll usually only have room for a small insert — and that’s where Style 1 tends to shine.

    If you’re happy to go up 1–2 cup sizes (or fill a bra that’s already slightly roomy)

    If you’re happy to move up a cup size or two, that opens up more options: Styles 2, 3, 6, 8, and sometimes 9a, depending on your bra shape and what kind of result you want.

    Using my size as an example:

    • I can comfortably fit Style 1 in.

    • In many of my bras (especially ones that aren’t the tightest fit), I can fit Style 2 and get a great result.

    • The same can be true for Style 3, and sometimes Style 8 — but in some of my bras, Style 8 can show a little above the cup because my cups are small. I don’t mind that if it looks smooth under clothing, but it’s not for everyone.

    You can always check the dimensions on the product pages, but do remember: silicone bends in the bra, so you can often use a style that’s 1–2cm bigger than your bra cup.

    A quick note on Style 6

    Style 6 isn’t an option for me in my normal cup size, but if I try it in a C cup, I can get a nice result in many bras — and it’s similar with Style 8 too, although I personally look bigger with that one because it cups the breast more fully and boosts the side profile ☺


    Bra brands and bra shape matter ( topics is just as important as style

    This is the next thing to consider: the bra itself. Brands and cuts aren’t born equal, so if you want a long-term great look, I’d absolutely recommend finding a bra that works perfectly with the enhancer you like (if you don’t already own one). The combination will reward you over and over.


    What about bigger styles?

    Style 7 and Style 9b are designed for a bigger, fuller boost, so they usually need a bit more breast (and cup space) to work with comfortably — on very small breasts they can feel like “too much insert, not enough bra.” If you do want a dramatic size jump, Style 12 (in the smaller size) can work, but you’ll normally need to wear a bra several cup sizes bigger because she’s a proper biggie and needs the room to sit smoothly.


    Browse the range

    You can browse all my breast enhancers (including styles that tend to work well for small breasts), and contact me if you’d like advice.

  9. Padded Bras - Help Or Hindrance?

    Posted on

    Image thanks to Image by <a href="https://pixabay.com/users/jackmac34-483877/?utm_source=link-attribution&amp;utm_medium=referral&amp;utm_campaign=image&amp;utm_content=627302">jacqueline macou</a> from <a href="https://pixabay.com/?utm_source=link-attribution&amp;utm_medium=referral&amp;utm_campaign=image&amp;utm_content=627302">Pixabay</a>

    The question of padded bras is one I get asked a lot, so I thought I'd pop a little blog post here as a help guide.

    Padded bras are great, they offer shaping an contouring to help give you a boost, but they are not without their issues.  They can generally only add up to 1 cup size, but many bra companies claim more than that. It's often a little misleading, as what they are refering to is the boost the more padded bras can give to a 30AA bra, so a relatively small amount of padding is needed to get them up to a 30B cup.  For a 38" bra however, a lot more padding is needed to get from an AA cup to a B cup. It's all about the volume, and there is only so much a padded bra can do and only so much oomph it can give. This oomph will also fade over time as the bra is worn and the fabric and foam filling stretch and squish.

    This is where my breast enhancers can really help. You can choose the size you'd like for the boost you'd like, and interchange them with different bras. I can boost you from half a cup size all the way up to 3 or more cup sizes for many sizes. 

    The big thing to remember howeever, is that that using breast enhancers with padded bras will often not work. If you have a simple padding all over, or a very small shaping inside the cup, you should be able to get great results, but if not you will probably find you have problems. This is simply becuase they are both trying to do the same job, giving you the same boost from the same place in the bra. The padding of the bra can push the enhancer away from where it needs to sit, giving you a rather uneven and possibly uncomfortable look.  

    Breast enhancers thrive in a smooth cup on the inside of the bra.  It can be a full cup, t-shirt bra, lace bra, lower cut bra, balconette style etc, and depending on the style and shape breast enhancer you go for, it should do the job perfectly for you in a normal bra. If your bra has some more defined shapping inside the cup however, you may find that buying a normal smooth bra to work with your enhancers gives you the great look you are after and opens you up to all the posibilties of the various breast enhancer styles and shapes. Given a nice smooth bra, my enhancers can boost you up or out in exactly the way needed to give you great results.

    If you need any advice at any time, just get in touch.
