The party celebrating the arrival of Burberry's new Spring menswear collection at Barneys on Monday night drew the likes of Gossip boy Ed Westwick, real-life socialite Poppy Delevingne, and all-around scenester Leigh Lezark, as well as the label's main man, Christopher Bailey. Despite the flashbulbs, it was a low-key affair—this being the first day back in New York for many going-out types after a month of international RTW. There was a similar sense of ease on the sartorial front, thanks to the label's trademark trench. "These hide a multitude of sins," explained Mary-Kate Olsen, who had spent the previous night at the late-finishing Metropolitan Opera gala. "They go over everything." Music was handled by Olsen's boyfriend, Nate Lowman, and fellow downtowner Leo Fitzpatrick. "Chris' people sent over some of his favorite stuff," said Lowman of the musical mix. Refreshments, which included an elderflower concoction, had something of a British flavor, too. "They keep taking the drink out of my hand when they take my picture," Bailey said. "But I like a cocktail—I'm English!" Not that he would have had much time to get into any trouble. Immediately following the party, the designer was heading to the airport to catch a flight to London, where he was due to shoot the campaign for the Fall collection. "That's the secret to staying busy," he said. "Get on a plane every night and go straight to work. Going out isn't an option."
