So I need, I mean NEED a bra for a bridesmaids dress that has a mostly open back. I have relatively large, heavy, and unfortunately not very firm breasts. (TMI maybe, sorry.) I ordered the dress with the largest bra cups available sewn in, but they nearly aren't big enough and offer minimal support. Has anyone found a solution for this situation? The dress is Dessy "After Six" 6740.
