Launched in 2001 and a mainstay in chic, young closets from New York to Tokyo, it hardly seems fair to call Marc by Marc a diffusion line. More than just a priced-down, mass version of the primary collection, Marc by Marc has its own sensibility. Whether it’s slouchy layers or retro prim, the look translates well for everyday, street, cocktails, and a stylish workplace. The silhouette is always key and ever-changing, and the brand boasts mix-and-match cheek that—in less capable hands—might look jokey. Waitlists for bags and boots are not uncommon.
