Triangle Breast Forms

My triangle breast forms are a lovely middle-ground shape if you want more forward fullness than my pear shaped breast forms, but not the perkier, more lifted look of my teardrop styles.

They have a wider, lower-sitting shape, so they tend to sit a little lower in the bra cup than my Pear or Teardrop forms, especially compared with Teardrop Style 1.

The clever bit is the concave back. It gives the form a little space to settle around your body, which can be especially helpful if you already have some breast shape of your own.
You do not need natural breast tissue to wear them, though. They can still work beautifully from a flatter chest if you like the wider coverage, softer slope and mid-projection shape.
Think of them as the “not too flat, not too pert” option. A bit of shape, a bit of softness, a bit of curve magic — without shouting across the room.

If you want the softest, flattest shape for a wider band and smaller cup size, my pear shaped breast forms may be your better match.
If you want a pert, lifted breast shape, have a look at my teardrop breast forms instead.

But if you want a realistic silicone breast form with wider coverage, gentle forward fullness and a lower, more adaptable fit, triangle may be your perfect pair.

These soft silicone breast forms can work well for crossdressers, trans and non-binary customers, or for mastectomy use.
They are also a good option if you are looking for realistic false breasts or breast form prostheses with a comfortable, flexible shape.

Priced per pair with delivery included.

Frequently Asked Questions

Triangle breast forms are a good choice if you want wider coverage with a mid-projection shape. They give more forward fullness than pear shaped breast forms, but are less pert and lifted than teardrop breast forms. They can suit wider frames, flatter chests, or customers with some natural breast shape of their own.

Yes. Triangle breast forms can work from a flatter chest, especially if you like a wider, lower-sitting shape with gentle forward fullness. They can also work well if you have some natural breast shape of your own, because the concave back gives the form space to settle around your body more comfortably.

This is partly personal choice, so it is worth taking a moment to think about your body frame and how you would like to present.

Teardrop Style 1 is usually best if you want a pert breast shape on a smaller frame.

Teardrop Style 2 is usually best if you want a pert breast shape on a wider frame.

Triangle breast forms are a good choice if you have some natural breast shape of your own, although you do not need to. They can also suit wider body frames or anyone wanting more mid-range projection.

Pear shaped breast forms are best if you have a mid to wider body frame and do not want a big cup size. They are wider and flatter, so they can also work well if you have some breast shape of your own and want the form to sit around it more softly.

Yes, but triangle breast forms are not the easiest style for covering the whole back with adhesive because of their shape. Boobylicious Tape is usually best used around the edges, where it can help reduce movement and give you extra security in your bra.
