Bad news never looked so good. An anonymous Gossip Girl blast hits about Serena (Blake Lively), clad in Dolce and Gabbana shorts, a sunny Madison Marcus top, Mulberry bag, Maloles shoes, and Fallon necklace, circulating a damaging rumor throughout Columbia's campus. Meanwhile, Blair (Leighton Meester), in an equally bright Nanette Lepore dress, Nancy Gonzalez bag, Mechante shoes, and a Tiffany's necklace, tries and fails to become a powerful businesswoman's assistant. Will the two girls be able to undo the damage? They're certainly dressed for success! Tune into the CW at 9 p.m. EST Monday night to watch the episode, and click through the photo gallery for head-to-toe credits of what the gals will be wearing!
