Cute BM dresses!

ModCloth just recently brought this dress back in stock, and I just love the draping detail at the top and that you can wear it beautifully in two ways!  I think it'd be adorable for bridesmaids, but is it too casual?  Accessories would be so key here.  I'd want this for a beach wedding and would have the BMs wear this in varying shades of blue (or whatever theme color I'd choose).

I am also inspired by Cinderella Project's entry on mismatched BM dresses.  Lovin' the mixture of colors look, especially when working with a monochromatic palette:

 

The trouble with doing mismatched BM dresses is figuring out the uniformity aspect: how do I set it up so that the girls still look like my ladies?  Cinderella Project suggests sticking to the same fabrics.  I'd probably also ask that the ladies stick to the same length (likely knee-length) to help with the uniformity.
