The Metropolitan Costume Institute Gala is known for its impressive celebrity guest list and Monday night's bash, which celebrated Miuccia Prada and Elsa Schiaparelli, was the most star-studded one yet.

And while the red carpet was a sea of stunning designer gowns, a few A-listers stood out in truly memorable looks.

Jessica Alba wore the night's most popular -- and flashiest hue -- stepping out in a gold Michael Kors gown.

Scarlett Johansson went all out in a strapless Dolce & Gabbana gown with a tulle mermaid skirt and embroidered bodice.

Newlywed Carey Mulligan, who was one of the event's hosts, dazzled in a sequined silver-and-gold Prada halter design.

Nina Dobrev made her first Met Gala appearance in a black and gold silk chiffon Donna Karan Atelier gown with an elegant train and accessorized with H. Stern earrings.

Beyonce showed off her incredible post-baby body in a sheer black embroidered Givenchy Haute Couture gown with a purple ombre feathered train.

Emma Stone wore a custom red Lanvin above-the-knee dress hand embroidered with crystal flowers.
