Implant Bottoming-Out is seen when the implants end up too low on the chest wall and the nipples end up positioned too high on the breast mounds, tending to pop up out of a bra or bathing suit top.
Bottoming out is where the implant doesn’t sit in the pocket that has been made for it. You will know if it happens because your boob will become an odd shape and as above says your nipple will look alot higher up x
