I'm a reasonable build (5'7'' and about 9.5 stone) but I seem to have loads of fat under my arms and when I wear a properly fitting bra it really digs into the fat and looks awful. To try and diminish the effect I'd have to wear a bra that didn't give me proper support as it would be way too big around my rib cage. Does anyone have any advice as to what I could try, probably in terms of exercises to try and tone up that area, if that's even possible?????
