Where to Find Bra?

I was wondering if anyone could help me? I am having a really hard time finding the right bra to wear with my wedding dress. I need a long line bra. My wedding dress has a diamond opening in the back and if I was to wear a regular bra the clasps would show. I can not find one that has enough support and is low enough for the dress. HELP!! P.S. It can have straps it does not have to be strapless.

Several places to try: David's Bridal (they are nationwide) said they have a one piece panty/bra combined that has lots of support but has a low waist in back. It is strapless and comes in sizes 32 to 42.

Another suggestion (from a very large breasted friend of ours) is to go to a high end (good quality) department store and check with the lingerie dept. They should have bra specialists. They can measure you and if they don't have what you need in stock they can special order it (special made or from their catalog of bras). She said she has her bras special made because she needs lots of support and had the same problem as you.
