Although Sunday was the official last day of Paris fashion week, Chloé's fragrance launch Saturday night—complete with towheaded spokesmodels Chloë Sevigny, Anja Rubik, and Clémence Poésy —was as good a place as any to celebrate the week's close. "Now this looks like a good party," said Leigh Lezark, presumably an expert in the subject, as she climbed the sweeping, candle-lined entrance of the Hôtel de la Monnaie, the eighteenth-century neoclassical monument on Paris' Left Bank. Inside, a slew of fashion week-ers, including Mary-Kate Olsen and Jessica Stam, made good her sentiment.

At midnight, the London-based band the Kills performed, much to the delight of photographer Ellen von Unwerth and Lily Cole, the two faces that Kills songstress Alison "VV" Mosshart says she can always pick out at her gigs (" 'cause Lily is just so tall, and Ellen is always right up front dancing along and smiling"). But despite the Parisian decadence, live music, and free-flowing Champagne, one partygoer claimed she wasn't completely comfortable at the fête: campaign star and Chloé-clad Chloë Sevigny. "Don't get me wrong, I think this is a great party and all," the Big Love actress said, and then—motioning to a wall on which moving images of herself, Rubik, and Poésy were being projected—added, "But there's something a little weird about seeing your face 20 feet high anywhere." By the end of the night, though, caught up in a gaggle of friends, including Benjamin Cho, she seemed to have forgotten any misgivings.
