The Met Gala returns to the Metropolitan Museum of Art on Monday, May 5, drawing a bevy of A-list celebrities to the storied museum for one of the biggest red-carpet moments of the year.

For her Met Gala debut, rapper Cardi B made a show-stopping entrance in a Moschino gold and cream pearl-encrusted gown, complete with a halo headpiece and matching opera gloves. The sultry bodycon dress weighed 30 pounds and was made grander by a voluminous bustle skirt that opened into a train.
