Margaret found these lovely silk/cotton dresses at her shop in Burlingame. They're the nicest color with a universally flattering fit, satin lining, delicate buttons up the back and fabric covered beads in the front. And at $40 a pop with her discount, I get to treat my bridesmaids to their dresses.
The brand is Esley and they also come in ivory and kelly green. I couldn't find them online though.
