Thank you for the question and picture. Online consultants will not be of much precise help to you; you will be better off seeking consultation, when the time is right, with board certified plastic surgeons in your area. Ask to see lots of examples of their work and communicate your goals clearly.
Generally, some of the characteristics seen with tuberous breasts include a very narrow base, short distance from areola to inframammary fold, tight (constricted) lower pole of the breasts, relatively wide space between the breasts, "puffy" and areola and some degree of ptosis (drooping).
Generally, correction of tuberous breast anomalies involves breast augmentation with areola reduction / mastopexy procedure. The distance from the inframammary fold is increased (to create a more rounded out appearance). Proper implant positioning improves the distance (cleavage) between the breasts. The areola reduction helps to treat the pointed and "puffy" appearance of the areola.
I hope this, and the attached link, helps.
