How to Fix Uneven Teenage Breasts

Asymmetry such as you decribe are very common, and most of the time it can be improved a lot but no one has perfectly matching breasts. Since your breasts are small, the most likely approach would probably be implants with a larger one on the smaller breast, and a nipple reduction. In other situations, there may be a reduction of one breast, an implant on only one side, different versions of breast lifting, and so forth. Breast asymmetry is where seeing a plastic surgeon with experience can make a difference.

Depends on the degree of uneveness and what you want ultimately.  In general, breasts fall into 'sisters not twins' for symmetry.  Having said that, there is more than that going on here so either augmentation of one side with lift of the other, or reduction of the large side to match the smaller one.  Depending on how large you wish to be, you may wish augmentation of both sides, with lift of the larger side to try to even out size of areola and shape of breasts.  Talk to board certified plastic surgeons to get a full assessment and understand that as you get older you may require more work depending on your body changes.  I have done many of these types of cases, and it is always thrilling to see how happy patients are to get their new look and confidence!
