I had a BA 13 years ago. I am ready to replace and go bigger. (i originally got 475cc saline under the muscle. I'm hoping to get 600cc silicone) I hate that my nipples sit low on my breasts. My breasts dont really sag at all so iam not sure if I need a lift. also I love the fullness of the cleavage but I feel like I have no side boob or under boob at all and they aren't symmetrical ( what do you recommend?
