From the Met Gala to the Afterparty — See Every Celeb Who Made an Outfit Change!

Rihanna might have been the last to arrive on the 2021 Met Gala red carpet, but clearly, she was also the first to volunteer to throw an afterparty. The star invited celebs who attended the ball for an encore after the event, giving them the opportunity to make outfit changes. Meanwhile, Kacey Musgraves also played host at the iconic Boom Boom Room on top of The Standard, and LaQuan Smith hosted an "Under the Bridge" soirée with Teva as a sponsor, where you can spot Kehlani above.

While some people slipped into more comfortable clothing for the evening out — we see you in those sneakers, Lorde! — others went from gowns to sexy, cutout minidresses. Singer SZA even had two additional ensembles on hand. Meanwhile, you'll also see celebs who might not have been on Anna Wintour's list this year, but did make it out to celebrate with the crew after hours. Keep reading for a glimpse at what everyone wore for the nightcap.
