Bridesmaid Dresses

I do not want my bridesmaids to be in matching dresses or uniform colors.  I'm creating a color palette and each girl will be in a different, complimentary shade.  Each girl will get to pick her own dress within some loose guidelines- at the knee or above, fancy, no sleeves.  The pictures below are my inspiration for this, although none of them are in the colors I'll be using- jewel tones, like the picture above.

This picture was my original inspiration for the look- I LOVE it!

Thread Bridesmaids has a lot of dresses well-suited to this idea.

J. Crew is another good option. This picture is from the Fall 2009 catalogue.

My friend's wife shot this wedding that incorporates some of the same ideas.
