Last night, Georgina Chapman and Keren Craig enjoyed the perfect summer evening for a rooftop celebration to launch their Marchesa contemporary off-shoot: Marchesa Voyage. Suitably fancy guests mingled and sipped “light” fruity cocktails atop the swanky Gramercy Park Hotel while browsing displays of the new collection, which officially hits stores on September 1. We chatted with the designers about the new collection, pleaded with them for hints about their upcoming spring show (it half-worked), and pressed them for their thoughts on diversity on the runway.
