Whether you're a cross-dresser, transexual or a woman wanting to look somewhat larger in the breast size department, you'll need to figure out the bra size you'll need to order for your body size and the desired cup size.This simply app needs you to take 2 measurements of yourself (or get someone to assist) input these measurements, and viola you'll have your bra size, along with the required level of padding if you had no breasts.
