Recognize those lips on Markus Lupfer’s Fall ’11 sweater?

“They are Lara Stone’s; I was going for the gap-tooth look,” Lupfer says of his latest take on his now-infamous “laughing lips” sweater—the designer’s leitmotif. The lips (as well as his other merino jumpers with cheeky slogans like “Sunday Best” and “Oh, You Pretty Young Thing”) are mainstays of the German designer’s collections. They make for a cool-girl look that’s won him legions of fans, including Gwen Stefani, Rihanna, and Lily Allen. Fellow appreciators Olivia Palermo, Edie Campbell, and Amanda Harlech’s daughter, Tallulah Ormsby-Gore, showed up to take in the scene at his Champagne tea party-turned-presentation, one that had Lanvin model Jono and Mary Charteris at the decks.

Models lounged around in Fall’s key pieces, including a fox-print silk dress juxtaposed with an edgy anthracite tailored jacket (“Country mouse meets city mouse,” Lupfer says). The carrot-leg silk trouser with the tweed waist detail looked effortless with a chestnut shearling jacket. A granddad knit cardigan worked well with a sharply tailored lace skirt, all complemented by tulle underpinnings and spotted-and-striped tights. The designer, who has collaborated with Topshop in the past, has a new partnership coming up, this time with a very famous artist. He’s keeping mum on the details for now.

But forget famous collaborators for the moment—Lupfer is doing plenty well all on his own. Hong Kong and Chinese sales are surging, and Lane Crawford recently dedicated a space for him in their online shop. And this year Claudia Schiffer was snapped by the paps wearing one of Lupfer’s camo-print sweaters. “She didn’t call us—she just bought the pieces retail,” Lupfer says happily of his countrywoman. “How great is that?”
