Thank you for your question and photos. An evaluation person would be required to properly advise you, however form your photos you appear to have very pretty and well proportioned breasts with minimal sagging or ptosis. If you are convinced that you would be happier being larger breasted, please keep in mind several points. 1. A large breasted woman who is anything but super thin ends up looking more like a "full figured" gal and not every woman likes that idea. 2. The larger your breasts the more difficult you may find it to find proper fitting bras and bathing suits, and may begin encountering interference with sports (running, tennis, golf), and ultimately experience neck, back and shoulder discomfort, the typical symptoms we encounter in women who seek a breast reduction. 3. If you have not had children but are considering getting pregnant in the future, your breasts may enlarge and stay larger, at which point you will be sorry you have implants. It is also true that after one or more pregnancies your breasts may enlarge and then get smaller than pre-pregnancy, at which point implants are often recommended for the "mommy makeover". If you are set on getting implants at present, a board certified plastic surgeon can advise you on size, however it would be important for you to come prepared with photos of women's breasts you find attractive. This would act as an important guide for your surgeon. Finally, if you indeed choose to proceed with undergoing a breast augmentation, consider a Low or Moderate Profile implant with a volume probably not to exceed 350 cc's, perhaps even 200-300. Best of luck to you.
