The Anna Wintour Costume Center is a wing of the Metropolitan Museum of Art main building in Manhattan that houses the collection of the Costume Institute, a curatorial department of the museum focused on fashion and costume design. The center is named after Anna Wintour, the longtime editor-in-chief of Vogue, Chief Content Officer of Condé Nast, and chair of the museum's annual Met Gala since 1995. It was endowed by Lizzie and Jonathan Tisch. As of August 2017, the chief curator is Andrew Bolton.
