The Smithsonian’s National Museum of the American Indian’s George Gustav Heye Center in New York will host the final showing of the first large-scale traveling exhibition of contemporary Native American fashion, celebrating indigenous designers from across the United States and Canada, from the 1950s to today. “Native Fashion Now,” originally organized by the Peabody Essex Museum in Salem, Mass., explores the exciting and complex realms where fashion meets art, cultural identity, politics and commerce.
