Breast prostheses

Breast prostheses (aka: breast forms, fake breasts, prosthetic breasts, false breasts) are an external breast implant intended to mimic the look, feel, shape of natural breasts. There are many types, shapes and styles of breast prostheses; some attach directly to the skin and some use special bras to hold the prostheses in place.

Using breast prostheses is common among trans women and AMAB nonbinary people looking to appear more feminine, however this is not limited to just these two groups. Genderfluid people can switch between binding and using breast prostheses depending on how they wish to present on a given day.

Shape
There are five main shapes of breast form: oval (or teardrop), round, triangle, asymmetrical and a breastplate. There's two main shapes for the back of the forms too - concave (for those who have some breast tissue), and flat (for those without).

Oval/Teardrop
This is marketed as the "classic" breast shape

Round
Simple, and the easiest shape to aim for if creating your own

Triangle
Shaped more like a pyramid, these give more outwards.

If you're not buying one, how can you make your own?
