They say every 100-150cc is equivelant to about one cup size but as I say everyone bets different results, you just have to trust your surgion to give you the look you want. You also need to think do you want to measure a d cup or to actually be a d cup as implans look smaller than they actually measure. Some girls with my size only get a c and some even get up to a size e . Also the smaller your back size the further your implant size will do so I have been told . My surgion said I may get to a dd because I’m only a size 32 back but would look a large c or a small d. Jut have to see what happened really. Yea sure 🙂 xx
