Last week on Gossip Girl was the Thanksgiving episode called Blair Waldorf Must Pie!
The episode went through flashbacks of when Serena was a wild party girl and how she interacted with her friends.
Many of you probably noticed Blair's amazing, Victorian-inspired, Thanksgiving dress. Well, we found out the details. The dress is Marc by Marc Jacobs and its called the Dita Lace Mini Dress. It is no longer available online from Sacks but you can probably still get it in stores.
