Thank you very much for your question and photographs. From your pictures, it does appear that you could benefit from a mastopexy, or breast lift, which will raise the sagging breast tissue to a higher, perkier position on your chest. When combined with implants, your breasts will see an increase in fullness, with better shape and volume. Additionally, your nipple/areola can be resized and reshaped, to better match the proportion of your breasts. Unfortunately, there is little that can be done to bring your breasts closer together, creating more cleavage. I suggest scheduling a consultation appointment with a board certified plastic surgeon, experienced in breast augmentation procedures. At this time, he/she can show you before and after photographs of recent patients, helping you to visualize the potential results that can be obtained through an augmentation and/or mastopexy.
