COPY KARL: Arm-in-arm, Cory Kennedy and Peaches Geldof arrived at Karl Lagerfeld’s show dressed as the designer and his muse, Lady Amanda Harlech. “I’m the gothic wife to Lagerfeld,” explained Geldof, who had tucked fresh daisies behind her ears. “She’s my muse,” chipped in a suited and booted Kennedy, as she donned Lagerfeld’s requisite shades. “I’m still channeling,” quipped the real Harlech, who was heading straight back to fittings ahead of Chanel’s show on Tuesday. Harlech’s daughter, actress Tallulah Ormsby-Gore, said she’s jetting to Cuba in July for classes at the Cuba International Film School. “I’m not interested in doing any fashion projects: It’s acting, acting, acting,” she said. Au contraire, fellow budding actress Lou Lesage, Anne-Valerie Hash’s longtime muse, is also the face of New York-based label Jill Stuart. “I have no movie projects,” she said. French actress Delphine Chaneac, meanwhile, is in talks to shoot a campaign for a Swiss watch brand. Chaneac will next be seen in “Verso,” a Swiss movie where she plays a prostitute, a part she almost missed when the director, Xavier Ruiz, saw her bald head. (She had to shave her hair for her role in this year’s science fiction movie “Splice” alongside Adrien Brody.) Chaneac’s funky crop won through – and she didn’t have to wear a wig. Spanish actress Elsa Pataky just wrapped up shooting “Mr. Nice” with David Thewlis and Chloë Sevigny. Music folk rounded out the front row, including Dutch Indie group Moke and post-punk Parisian act Neimo, who looked on as British electonic act Metronomy opened the show. Backstage, editors were agog to see Lagerfeld in a brown safari jacket. “It’s brown, but not Thom Browne. It’s Tom Ford,” he explained. After completing collections for fall/winter 2009, the designer will turn his attention to court costumes from 1650-1800. That’s the subject of a Chanel-sponsored costume exhibition opening at Versailles later this month, and he’s writing the preface. “They wanted something by a not-serious person,” he noted.
