It’s not really up to you, hun. The surgeon decides depending on how much breast tissue/skin you have. I have overs, and really didn’t want unders because of the extra healing time etc etc, but girls with unders are very happy on here. Don’t be fooled into thinking that only unders give you a natural look, because overs can give you that too. Just depends how big you wanna go, how much skin/tissue etc. x
