It depends on the woman - I've dropped 2 clothes sizes (nearly 3!) and lost 29 lbs with weightwatchers as well as getting some exercise (finally - lol!).
My back size on my bra has dropped from a 40 to 34, however my cup size has increased
I've been tracking my measurements and have lost 6 inches under my bust, but have only lost 1 inch from around my bust so I'm now wearing an F cup


.
Any way I can get them a bit smaller?
