Ideal Breast Cup Size my Frame?

I am a Plastic surgeon in London and thank you for your question. There is no ideal cup size and you should see a qualified Plastic surgeon who will be able to guide you through this process. It is more important to have a good shape after a reduction as excessive reductions can make the breasts look flat. 

The ideal breast cup size varies from woman to woman. Every woman has a different idea in her mind of how she wants her breasts to look, and therefore it is hard to tell you what size is best for you without examining you in person and hearing what you envision as the best breast size for yourself. You want breasts that are in balance with the rest of your body, which is probably much smaller than a 38DDD for you. I recommend consulting in person with a board certified plastic surgeon, so you can get an answer that is truly correct for you!

The average American cup size is C.   You can work with your plastic surgeon to discuss your goals.  Most women request C cup, but it is perfectly OK to ask for a D or a B, as long as you satisfy the insurance company requirements.
