Of all the reasons that designer Sonia Rykiel's quirky exuberance remains so endearing, it's her ability to make the most stoic models smile—even dance!— down the runway that's made her shows such a delight. 43 years into her career, the Rykiel's knack for conjuring up a Régine-worthy Eurodisco spectacle remains as ageless her kicky knitwear. Last night, the party came directly to the West Village's Bobo, where teen icons (Gossip Girl's Leighton Meester and Kelly Rutherford) and fashion folk (model Siri Tollerod and jewelry designer Eddie Borgo) celebrated the stateside arrival of Rykiel's capsule collection for H&M. In keeping with the label's "models storming the dancefloor" spirit, model and Rykiel runway favorite Chanel Iman played DJ, an opportunity the 20-year-old described as "too fun" to refuse. With help from her boyfriend and friend Prince Peter, Iman kept her musical selections light and Euro-inflected, with Goldfrapp, La Roux, Little Boots, and Hot Chip making repeat appearances alongside Michael Jackson and the Rolling Stones. Asked how she went about setting up the night's atmosphere, Iman was girlish and direct: "I basically am keeping it spontaneous and choosing my favorites. It's very me!" As for her New York Fashion Week plans? She laughs: "It's way too early to think about! I just want to have fun right now." Rykiel's girls always do.
