Rihanna was one of the last stars to arrive at the Met Gala tonight, and boy did she not disappoint. We’re used to Riri rocking wild outfits, but this look was chic and refined. The black Tom Ford gown hugged her body in every right way, the neck line was simple and classic and the conservative long sleeves tossed attention to the sexy cut of the back. She kept her hair up and simple and her heels sky-high. We always expect the unexpected with Rihanna, and this move was no different. Her look tonight was timeless and glamorous but still totally her own.
