How soon after a breast reduction will I know my new bra size?

Most changes occur following breast reduction in the first several months. By the third month you will be close to your final bra size, but the final result may take up to a year.

Thank you for the question. I suggest that you wait to evaluate the final result/size of the surgery (and go bra sizing/shopping)  when you are about 6 months to a year out.I would also suggest that you do not base your satisfaction with the results of surgery on a specific cup size,  given that this is somewhat arbitrary and dependent on who makes the bra.Hopefully you will  enjoy the physical, functional, and psychosocial benefits of the  breast reduction procedure.Best wishes.

It takes a while for the breasts to settle after surgery. I allow my patients to wear regular bras at 4 weeks but make them wait 3 months before wearing underwire bras. By this time the new breast shape and size is pretty much determined.
