Models, drag queens, and makeup lovers lined up at Industria Superstudio last night to fête François Nars and his new tome 15x15. The face painter-cum-photographer's third picture book stars a bevy of his friends—Olivier Theyskens, Amber Valletta, and Isabella Rossellini, among them—each of whom models a particular Nars product to showcase an iconic moment in time. "It's the same idea as my other books," the makeup artist said. "Taking people and transforming them."

Marc Jacobs and Daphne Guinness co-hosted the evening, and it's hardly a surprise that their portraits were crowd favorites. No, the designer wasn't wearing Nars' Dovima red nail lacquer and matching lipstick like he does in his sixties-era Richard Avedon-inspired picture (instead, he was sporting eyeliner, mascara, and bronzer), but Guinness did pluck look 24 and a pair of sky-high lobster-claw platforms straight off Alexander McQueen's Spring runway for the occasion. "You can't take your eyes off her!" Phillip Lim said as the heiress made her way around the crowded party. "Are those hard to walk in?" we asked. "Not for me," she said coolly. "I've had years of practice."
