I may not be much help because we found this David's Bridal dress at a thrift store for $15...but I wanted to second the www.girlsdressline.com recommendation! I have a friend who has bought many dresses there & been very happy.
@ Laura and Tiffany, where did you get your dresses?
My dresses that I thinking about getting come from Etsy. The one for my niece (1st pic) will cost me about $101.50 and the one for my daughter (2nd pic) will cost me $109.90. I love the dresses but I would like to paid a whole lot less.
Mine are just like NewLife's. One of my bridesmaid actually just chewed me out for ordering them off line -- because she knows how to make them! So it will only cost me materials. (And a little extra for her gift!)
