Fashion icon Carine Roitfeld celebrated a dance-inspired second issue of her latest CR Fashion Book with a samba party at Casa Lever on Tuesday. R&B songbird Ciara and Roitfeld were led onto the dance floor by performer Lil Buck, who showed off moves to a Brazilian band. Carine’s kids, Julia Restoin Roitfeld and Vladimir Restoin Roitfeld, greeted guests including models Irina Shayk, Karlie Kloss, Lily Donaldson and Doutzen Kroes, designers Joseph Altuzarra, Olivier Theyskens and Riccardo Tisci, and ballerina Misty Copeland. Carine explained an obsession with ballet in her mag as one of the last art forms “with pure motives . . . ballet stars rarely sign huge endorsement deals or become world-famous.”
