The photos were reviewed and show small-volume breasts with a short or tight-looking lower pole and limited tissue below the nipple area, but photos alone cannot diagnose whether the breasts “developed properly.” Breast shape varies widely, and many patients naturally have less upper-pole fullness or less tissue beneath the nipple without it meaning anything is wrong with them. One possibility to discuss with a plastic surgeon is a mild constricted or tuberous breast shape. This can involve a narrow breast base, a higher or tighter inframammary fold, less lower-pole expansion, asymmetry, or a puffy areola. You do not need to have every feature for it to matter surgically, and the diagnosis is best made by measuring the breast base width, fold position, nipple position, skin envelope, and chest wall in person. If your goal is more fullness and a rounder lower pole, breast augmentation can help, but implant choice and surgical technique are important. In a tight lower pole, an implant alone may not fully correct the shape unless the pocket and fold are planned carefully; some patients need lower-pole release, careful fold adjustment, fat grafting, or a limited areolar/lift procedure depending on the anatomy. I would consult with a board-certified plastic surgeon who has experience with constricted breast correction and ask specifically how they would create lower-pole shape, not just what implant size they would use.
