Someone already posted that Priscilla of Boston is having a sample sale, but I just wanted to say I was just there this evening and they still have a good selection of bridesmaid and wedding dresses. The BM dresses were all $19.99 and I picked up a really cute cocktail length one to wear to other weddings I'm going to this year, and maybe my RD. They seemed to have a lot of nice gowns, too, for good prices, but I didn't let myself look to closely since I have a dress. Mostly size 8s though.
HTH someone! The sale ends tomorrow (Friday)
