400cc moderate plus too large for me? (Photo)

Hello and thank you for your question.  The
best advice you can receive is from an in-person consultation.  It would be helpful to know your individual breast measurements in order to determine if 350 or 400cc would be a better choice 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.  

Best wishes and good luck.

Hello,400 cc implant will not only look really big on your 5 foot frame (but that's a matter of taste, and not what is crucial to me as a surgeon), but they will likely exceed your anatomic soft tissue limit, leading to complications and reoperation. Your surgeon should size you (it's not just breast base width or BWD) to confirm anatomic capacity, and you should use sizers in the mirror to determine your anatomic goal, if achievable. Best of luck!
