Lily Allen and her sister Sarah Owen are gearing up for the launch of their Lucy in Disguise vintage boutique in Covent Garden later this month by giving London shoppers a taste of what’s to come. On Friday, the duo launched a pop-up Lucy in Disguise boutique in London’s Selfridges. The space carries pieces by Bill Gibb, Ossie Clark and Lanvin, which customers can buy, or alternatively hire for 20 percent of an item’s retail price. The pop-up space will also house an Illamasqua makeup counter and a hair dressing area, designed so shoppers can step out of the store ready to party in their new purchase. The boutique will be open through Sept. 15, when a permanent Lucy in Disguise concession will bow on Selfridges’ second floor, in its women’s designer wear area. Come Sept. 16 the duo will launch a 3,000-square-foot Lucy in Disguise store on King Street in Covent Garden with areas devoted to different eras, such as the Twenties and the Fifties, while the space will also have a Bumble and bumble hair salon, a Grey Goose vodka bar and a PlayStation den for any men who wind up in the store. And a ready-to-wear collection is in the works, too. Also, Allen and Owen have designed a Lucy in Disguise London collection of vintage-inspired pieces, which is planned to launch for the spring.
