32B Considering 400cc... Too Much?

Based on your photos, this size implant will likely make you a C/D bra cup size. If this is your goal then it may be appropriate. You should discuss this further with your surgeon to determine if this is proportionate to your body. I use 3D imaging to determine the best implant volume for my patients and it gives a very accurate visual idea of the final result.

Best wishes,

How big do you desire to be?  In order to make an accurate size recommendation, I would need to assess your chest wall and breast mound measurements and characteristics.  Unfortunately, there is not a general rule of thumb or objective criteria to implant selection.

Your plastic surgeon will perform several measurements of your chest wall and breast anatomy and determine a range of implants that both fit your chest wall and reach your desired goals.
The next step is to try on this range of implants in the office with your doctor.   The key to this success is showing your surgeon the body proportion you desire with a bra sizer and allowing your surgeon to guide you to the right implant.   It will be much easier to communicate in implant cc's than cup size when determining the appropriate implant for you.
I wish you a safe recovery and fantastic result.
