No one can predict exactly what bra cup size you will end up wearing after reduction of a certain amount of tissue. Having said that, 200 g is generally too small of a volume reduction to be functionally or aesthetically “significant”. I would suggest that you communicate your goals clearly with your carefully selected plastic surgeon. In my practice, I find the use of goal pictures helpful during this communication process. Stay away from the use of cup sizes as a reference point, as this reference point may be a source of miscommunication.For most patients, I recommend that they try to decrease the size of the breasts such that symptoms are relieved as much as possible; yet the breast size remains proportionate to the remainder of their torso. I hope this, and the attached link, helps.
