"One day that will not arrive on schedule will be the opening of the Costume Institute's exhibition, About Time," she wrote in a letter that also served as Vogue's endorsement of Joe Biden for president. "Due to the unavoidable and responsible decision by the Metropolitan Museum to close its doors, About Time, and the opening night gala, will not take place on the date scheduled. In the meantime, we will give you a preview of this extraordinary exhibition in our forthcoming May issue."
