When I was a bridesmaid, it cost $180 from jcrew.com, plus alterations, and I never wore it again. What a waste of money. For my wedding, I had my bridesmaid dresses (http://www.inweddingdress.com/style-bc131.html)made by
inweddingdress for $49 each. No alterations needed and it was a dress that both wore numerous times after.
