Could you tell me where I am going wrong if the straps are slipping off my shoulders. Massive massive knockers, have bought bra according to "the rules" but it rubs under pits and the straps are forever falling off.
Is it a style thing? If so please recommend a bra for a 36jj (and a tankini if poss!)
I am most grateful. And also apologise that it isn't such a short one after all.
