I know Jessica McClintock is having a sale today and now that I can't get on the site I don't remember the specifics. Its either dresses from 30, 40, 50 DOLLARS or 30, 40, 50 percent off. But I think its dollars!
Also David's Bridal is having a sample sale today on Bridal Gowns and Bridesmaid Dresses!!!
Either store would be good to look for those Christmas party dresses/gowns or your bridal party's attire!
