I ordered my normal size, 32DD, and it was WAY too small in the cups. The band was pretty snug on the last (most loose) set of hooks, but I'm sure that part would have stretched a bit and been fine. The cups, however, didn't have nearly enough room for the girls - they were spilling out at the top and sides. The bra felt great otherwise, I'm really disappointed because there's no DDD. The top clasp wasn't a problem at all, I just undid it, put the bra upside-down backwards and did the hooks like I normally do with my regular bra, then twisted it around front and pulled the shoulder straps up and over. Then I reached up-and-over and did the top clasp, no biggie. I don't think I'm abnormally flexible. I would love to have this bra but I had to return it, and they don't seem to offer the size I need.

3/10/13: Ordered again at a 32E as a commenter suggested, still too small in the cups. No spilling out the sides this time, just the top. I'm going to order up again - I REALLY want this bra, but it sure is a pain getting the size right.
