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.

Singer SZA even had two additional ensembles on hand.
