What can be done about the shape of my breasts and areola? Tanner IV stage (photos)

From the photos it appears your breasts are small, but normal. The areola has slight herniation which can be corrected surgically if desired. It doesn't appear that the nipples are inverted. I have included a video about breast augmentation if that is something that interests you.

If interested in implants I recommend an in person consultation with a plastic surgeon to discuss your goals and be measured. After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements with different size and profile implants. You get to see actual results and the surgeon's experience and not a virtual idea of what can be achieved. Women tell me that this process is very helpful. There is always the possibility that the implants might be seen or felt on the side of the breast or under the breast where there is little or no muscle.

First, if you are 18 or older, the Tanner classification does not relate to you. Second, when you post photos of your breasts on this site, please do so with your arms down by your sides. Third, the size of your breasts is related to genetics, hormones, and weight. Genetics you cannot change and not all ladies develop much breast tissue with weight gain. If you want larger breasts, go visit with a plastic surgeon and discuss your concerns and options.
