Gossip Girl "Salon of the Dead" Wardrobe

Wear Serena's Catherine Malandrino Longsleeve Navy Lace Dress ($395) — which she wore with Jean-Michel Cazabat's velvet-embellished pumps — with a long beaded necklace, like she does in this scene, or throw on a rhinestone necklace for shiny impact. For a work-appropriate version, wear black tights, booties, and a black blazer to sharpen things up.
