Okay, I've bought a bodycon cold shoulder dress but it is also tie front so there's a gap under the bow (so you can see a bit of the bra). I really need help finding a bra because it needs to be strapless, plunge style and has to be a 28 band! I have to wear a 28 band bra on the tightest hook and most bra brands start at 32 
Please help!
