If you get one where they cut the nipples open to insert the implant then you are going to notice them nipple scars a mile away. Nipples are the first thing people look at on breasts when a woman is topless.
I would get get the operation where they slice under the breasts so its not bait.
If you want to minimize scarring its best to have the incision in the armpit. There are no scars on the actual breast whatsoever.
