And that's all, folks! Gossip Girl bid adieu in a two-hour series last night. All ended happily in the Upper East Side: Gossip Girl was revealed (spoiler alert: it was Dan!), Chuck and Blair got hitched, and Dan and Serena got together in the end. And while the series ended, its fashion legacy lives on. To close out the show, costume designer Eric Daman dressed Georgina Sparks (Michelle Trachtenberg) in an embellished sequined dress with Danielle Queller hoops, while Blair Waldorf (Leighton Meester) wore an Elie Saab gown.
