When Carine Roitfeld launches a magazine, everyone pays attention. Saturday night, the former Vogue Paris editor feted CR Fashion Book with a long gown-only dress code (she opted for Alaïa, and let's just say we were dressed much more modestly), Ryuichi Sakamot piano performance (which was followed by a DJ set that included Kanye West and other Top 40 hits), and, of course, a lot of models. A lot.

Kate Upton, the magazine's first cover girl, was in attendance, looking glamorous and sultry in a low cut gown with smokey eye makeup and tousled hair.

After spotting Upton by the front entrance, we realized that this party had become a test: How many supermodels do you recognize? We planted ourselves by the front door and started playing. Karlie Kloss? There. Joan Smalls? Right next to her. Lindsey Wixson? Bar Rafaeli? Isabeli Fontana? Karen Elson sporting a brand new bob? You get the idea.

Although the models roamed throughout the party, Carine Roitfeld was still queen (she even upstaged Alessandra Ambrosio in an Angelegging contest). Check out the photos below to see more from the Mercedes Benz and Belvedere-hosted launch of CR Fashion Book at The Frick Collection in NYC, and let us know which model you think had the best style.
