Marc Jacobs launched his diffusion line Marc by Marc Jacobs in 2000 as a youthful complement to its big sister. With more of a sense of humor than its sibling, Marc by Marc Jacobs reworks design classics with fresh prints and a bold use of color. With cool Brit duo Luella Bartley and Katie Hillier now at the helm as Design Director and Creative Director, their cult shoulder bags are as highly anticipated as the mainline.
