To me, Gossip Girl's stylist's best creation is Lily van der Woodsen's dress sense. I could quite easily swap my entire wardrobe for hers. Always in very tailored, very classic dresses, diamond earring studs, a great necklace, hair swept up and sporting a glass of champagne, this character is the very essence of class and sophistication. I love the extreme polish and refinery to her look.
