Everyone Slipped Into Their Sexiest Looks For the Met Gala Afterparty

When designer Olivier Rousteing throws an afterparty for the Met Gala, you can bank on all the It models in Balmain minidresses. But they weren't the only ones to switch up their style after walking the red carpet.

While Beyoncé and her sister, Solange, slipped into the most casual high-fashion looks we've ever seen, hitting up The Gilded Lily with the likes of the Kardashians, The Weeknd and Naomi Campbell hosted a soiree at Up & Down, where we saw Bella Hadid try her latex club look on for size. Scroll to see how everyone dressed up to get down after the ball.
