I would like them to be perky and firm. How many cc's would be right for me?
Based on your description, your size, and your goals, it sounds like what you really need is a mastopexy, or breast lift. Implants alone will not give you a lift and will only serve to make your areola even larger. You will have larger sagging breasts and probably be even less happy. A breast lift involves additional surgery that results in a scar around your areola and then from your areola down to your fold under the breast. You may then also need a scar in the fold itself, depending on how much excess skin there is. You really need to consult with a reputable, board certified plastic surgeon to get the best advice.
