Yep, this is one only ISawItIn.com had for the longest time, thanks for a great reader who helped us research it. Well, to actually buy it we contacted the designer, emailed back and forth and yes..there are (were?) a few of these dresses left, their called the Flag Dress. Something is wrong with their site but catch Rachel at her MySpace page. She told us they only had a few left during Fall 08.
Now the necklace in this scene is from designer designer Masha Archer. Visit her site for more info and here are some inspired styles a few reader's suggested.
