Under the muscle is generally for patients with barely any breast tissue and give a more ‘natural’ look as the muscle is over the top of the implant which hides the top of the implant. Overs are where they’re placed under your breast tissue but over the muscle, generally for patients with enough tissue to cover the implant or for people who have lost fullness and want to fill out the top of their boobs.
I had overs even though I was a 32a and think they look natural, think your surgeon will be the best to decide for you ????xxx
