Bridesmaid Dresses

So I haven't put much thought into what my girls are going to wear.  I know it will be most likely be a long dress, but I don't know color/style etc.  My cardinal rule is let them pick their own shoes and jewelry, but I want to do something different!

I have been playing around on The Dessy Group Website and you view each dress in anywhere from 10 to over 100 colors.  It is such an easy way to run through all my ideas.  Between the 7 brands of dresses they offer I think it is going to be impossible to narrow it down. 



This is one of my favorites

I am really excited to pick them out.  What other brands do you recommend?
