The First Monday in May follows the creation of The Metropolitan Museum of Art's most attended fashion exhibition in history, "China: Through The Looking Glass," an exploration of Chinese-inspired Western fashions by Costume Institute curator Andrew Bolton. With unprecedented access, filmmaker Andrew Rossi captures the collusion of high fashion and celebrity at the Met Gala, one of the biggest global fashion events chaired every year by Vogue editor in chief Anna Wintour. Featuring a cast of renowned artists in many fields (including filmmaker Wong Kar Wai and fashion designers Karl Lagerfeld, Jean Paul Gaultier and John Galliano) as well as a host of contemporary pop icons like Rihanna, the movie dives into the debate about whether fashion should be viewed as art.
