So I got my dress and it has a sweetheart neckline with illusion lace that takes it up to a bateau neckline. It has boning and cups sewn in but it doesn't offer enough support (I'm a 34DDD). The back isn't super low, but it still switches to the illusion lace a couple inches below where my normal bra's band goes around my back. Any bustier girls out there have any suggestions for what I can do to get the support I need? Would a bra with a clear back and clear straps show through the lace? Anyone know of a supportive low back strapless bra?
