It was a starry night at New York City's Metropolitan Museum of Art, where the Costume Institute hosted its annual gala. This year's celebratory fête was for two iconic Italian designers, Miuccia Prada and Elsa Schiaparelli. The two were honored with an exhibition and video, Schiaparelli And Prada: Impossible Conversations. Of course, the pre-show of the night was the gala's posh red carpet presences. All eyes were on Beyoncé's post-baby body in a dramatic see-through Givenchy Haute Couture gown and her sister, Solange, in a bold yellow one. And the list of fashionable celebs in attendance goes on. Here's a look at the night's extravagant glam gala.
