From a Washington Post story by Rachel Tashjian and Valeriya Safronova headlined “It’s a Vogue world after all”:

On Wednesday, the Metropolitan Museum of Art and Vogue shared news that’s as closely guarded as a state secret: the theme for the Costume Institute’s Met Gala, held on the first Monday in May.

“Sleeping Beauties” will celebrate the ephemerality of fashion and its sensorial pleasures — sound, scent and pure emotion. The reveal kicks off months of anticipation — designers, stylists and celebrities planning ensembles and guest lists, with Vogue’s print and digital dedicating pages teasing the exhibition.
