Beyonce red carpet gown costume met gala see through

Who is the fairest of them all?

The biggest and the brightest stars stepped out for the annual Met Costume Institute Gala in NYC on Monday night, and we're literally drooling over some of their custom couture gowns!

The theme of the night was "Schiaparelli And Prada: Impossible Conversations" and of course, most of the hottest A-listers chose sparkly Prada pieces to wear to the exclusive Ball, which was held at the Metropolitan Museum of Art.

New mom Beyonce left little to the imagination in a see-through black sparkly lace ensemble with purple feather accents by Givenchy, while Liv Tyler looked equally stunning in an all-black design by the same French label -- she's also the face of the brand's perfume line!

Milla Jovovich channeled1920s style in a red Marc Jacobs gown with black accents, while celeb stylist Rachel Zoe, who designed Karolina Kurkova's sequined space-age look, stuck to a clean white fringed dress with a statement necklace from the Rachel Zoe Collection.

Glee star Diana Agron stood out from the crowd in an emerald green chiffon creation by Carolina Herrera, and Diane Kruger's purple Prada gown had such a massive feather train, she needed an extra hand just to carry it!
