Louis Vuitton recently fêted the launch of its Stephen Sprouse collection. Marc Jacobs told New York's Harriet Mays Powell his inspiration for the line came from a number of places. "I thought, well, how do we deface the monogram to make something more rebellious? More punk?" Jacobs said. During a visit to Charlotte Gainsbourg's apartment, he noticed a Louis Vuitton monogram trunk painted black, and the idea gelled.
