I'm planning on living in them in the fall!"

"I loved the boots-I want every single pair!" said Jessica Szohr, when asked to name a few of her favorite things from the Jill Stuart Fall 2010 collection. Joining Szohr to scout fall must-haves during the show was her Gossip Girl co-star, Michelle Trachtenberg.
