For inspiration this season, longtime connoisseur of sound, Hedi Slimane, unearthed his “London Diary,” a black-and-white Polaroid series captured in London’s brimming musical underground. But for the collection’s graphic range of bags, Slimane looked beyond the borders of his adoptive city, recruiting a duo of globe-spanning emerging artists: Chicago-based Anneli Henriksson, and French-born, Berlin-based David Hominal. Together, they comprise a portable metaphor for Slimane’s vision: Hominal’s is a brooding take on negative space, while Henriksson’s is expressive and all-seeing.
