Hello and thank you for your question. You are a great candidate
for a breast augmentation.  It would be helpful to know your individual breast measurements in order to determine if 400cc is a good size for you.   The size, profile, and shape of the
implant is based on your desired breast size/shape, your chest wall
measurements, and soft tissue quality.  This decision should
be based on a detailed discussion with equal input from both you
and your surgeon.  This entire surgery
can be performed with a small incision technique.  Make sure you
specifically look at before and after pictures of real patients who have
had this surgery performed by your surgeon and evaluate their results.  
Best wishes and good luck.

Thank you for your question. It is difficult to make a recommendation about size of implants without a proper consultation. I recommend consulting with another board certified plastic surgeon(s) that offers technology that can do 3D simulation breast imaging so you can view the outcome not only related to your breasts, but to the entire body as well.
