What is a Good Breast Size for Me? I Am 5'8''/5'9'' and Weigh 132 Pounds Medium Frame.

   In general, the maximum size of the implant placed can be determined by chest wall measurements.  Then you can try on sizers in a bra to give you an idea of the volume you would like.   The profile can then be determined based upon the volume you would like.  Kenneth Hughes, MD Los Angeles, CA

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.
