I had very little breast tissue to work with & went under the muscle, I kinda thought if I went over then it would look very fake but seem lots of overs that don’t look at all fake … Mine are 350cc unders & they’re exactly what I wanted, think if you want more size make sure you go a little bigger cc to account for any loss under there but for me I just wanted some fullness. I’m really happy with mine
Got pictures on my page, feel free to have a look
