I'm 32AA with 400cc silicone unders. Am I going to get bigger? (photos)

At your size and weight, the implants that you had placed are likely on the upper limit of what your tissue could tolerate.  You have a significant amount of dropping to do, which will affect your ultimate look and size.  It takes several months for your final appearance to be reached.  I think that with time. you will develop a more natural shape, and the bra size that you wear will likely be a a 32 C/D.  I advice my patients to not be so concerned with what the actual bra size is.  Different manufacturer's bras will fit differently.  The important thing is that you be happy with your look.  I think that you are off to a great start.  Best regards.The information above should not be considered a substitute for consultation with a board-certified plastic surgeon to address individual medical needs. Your particular facts and circumstances will determine the plastic surgery treatment which is most appropriate for you.

The volume of the implant is artificially supported by swelling is demonstrated in the photograph. Is this relaxes distribution of volume will change. It make take several weeks before you can appreciate the final breast appearance.

Congratulations on your breast surgery.  It is still to soon to assess your final breast size - they will change for at least several months.
