Would Miraculous Push Up Bra work on a flat chested person? 10 pts?

the miraculous bra's add a cup size...maybe even 2 cup sizes. They are huge...stuffed thick with padding. Iv tried one on before and it was unrealistically big, unless you already have alot of boobage its going to be hard to get a seemless look since all of your bust will be fake. I would recomend the VS gel curve push up bra's since it works with what you already have instead of fabricating all of it...it will look more natural and since your already small the murasculous bra will not fit well
