bridesmaids' dresses

Some ideas for Bridesmaid dresses...all from David's Bridal. I like the idea of picking a color palatte and having the ladies all pick dresses from that group of colors. I definitely want them to be able to pick dresses that work best for their body type. I like the idea of a jewel color palatte...marine (navy), purple, burgandy. I know it's not super-summery but they're my favorite colors!
