Contingency plans in case of volcanic eruption are scarcely the stuff of everyday life in London, but events in Iceland inspired knock-on ingenuity as airports across northern Europe were closed by a drifting ash cloud yesterday. Harrods fashion director Marigay McKee mentioned a friend who’d hailed a black cab outside Heathrow to get him to his skiiing holiday in Salzburg on time. (That’s a two-day drive, BTW.) She was co-hosting a party to celebrate the opening of a new Acne boutique in Harrods with Acne CEO Mikael Schiller. He’d flown in from Sweden just ahead of the cloud, but the rest of the Acne team weren’t so lucky; they stayed stranded in Stockholm. Still, the party at the boutique and the dinner afterward at Mr. Chow didn’t disappoint. Schiller declared that an in-store in Harrods fulfilled a longtime ambition for the little company that could. (He also remembered an earlier moment in Acne’s relationship with the retailer, when they had to come up with a convincing acronym to explain why the company was named, to English ears at least, after a pimple.) Sarah Mower, Gabriele Hackworthy, model-turned-designer Ben Grimes, Acne Film’s Rikard Svensson, Acne Paper‘s Duncan Campbell, and Acne communications director Anthony Kendal’s posse of Australian billionairesses helped fête guest of honor Husam El Odeh, the London artisan whose jewelry is one of the city’s small, seductive pleasures. He has created little shields of silver for the thighs, knees, calves, and back pockets of a pair of Acne jeans. Tron-like articulation is right on trend with the movie remake on its way, but the notion of any added protection may prove equally timely if Eyjafjallajökull continues to blow.
