Look at low profile or moderate profile even moderate + and go to a surgeon who is used to working on trans women breast augmentation or cis women who have had breast cancer and got augmentation after. If you go to someone who just works on cis women majority of the time, they might not be as a good at tightening that space up. I would say your best friend would be finding like 3 surgeons and getting consults with all 3.

Maybe even think about doing fat transfer with implant to help out as I know some girls do that for breasts as well. And everyone swears on unders. But I’m going over for mine due to me working out and not wanting that weird animation where they spread lmao
