What size will I be after removing one pound from each breast? I'm currently a full 36 DD. (photo)

Generally  speaking plastic surgeons don't refer to the amount of tissue that's being removed in pounds however about 500 g equal to 1 pound and will reduce your breast size to a C cup probably. With that said I believe that you may need a little bit of replacement to give you an aesthetically appealing breast especially since you had massive weight loss. I believe that removing the excess skin and fat will help you with your back and shoulder and neck pain. 

Thank you for your picture and questions. Discussing cup size is not always a fruitful discussion and bra cup sizing has no standardization. This is probably why your surgeon gave you a vague answer about a B or C cup, because it depends on where you shop. Your surgeon plans to remove a specific volume from the breast, based on the estimation of "a pound" I assume she is planning on removing somewhere between 400-500 cc of volume per side. This may be based on insurance criteria or other factors, but you would have to discuss with her why she made that estimation. That being said, there is no conversion between what is removed in terms of volume and what that means for cup size. The goal would be to reduce the breasts enough to meet criteria or to improve your symptoms while also leaving your with a more youthful appearing breast that matches your frame. If you are worried about being too small, discuss with your surgeon that you would like to retain as much volume as possible within the requirements. If you are ultimately unhappy with the volume, you can always consider a small augmentation later. With the vast majority of reduction patients, this is not necessary as they are usually very happy!Hope this helps!

can be challenging and rather than focus on what cup size you will have, its probably more important to discuss options on how you can best fill out your upper poles as they are hollow now and if nothing is done to help that, will remain hollow.  Also nipple grafts would be recommended with your presentation and the amount of ptosis that you have and your surgeon should be acquainted with that technique and better, even discussed it with you already.  In general, with a standard reduction, most of my patients end up being 1-2 cups smaller, unless the resection was intentionally aggressive.
