Question: what size bra should i get when nursing?
Answer: Fitting Your Nursing Bras Set 1: As a good rule of thumb: Add one cup size and one back size onto your usual pre-pregnancy bra size. ... Set 2: Take your pregnancy bra size, add 1 cup size and subtract 1 back size. So if you are wearing a 34D near the end of your pregnancy, you should try a 32DD for nursing.
