I put together a collage of few styles of dresses I like from David's Bridal ranging from $159 to $199. I like the color "biscotti"...it's not quite the champagne color I was originally thinking but I think it's a beautiful nude/soft purple color. I love the idea of the mismatch dresses. Each of the girls could pick out a style that they like and also have a little flexibility on the price range with the two different price points. I also think this color will pair nicely with a gray tux.
