The two-time Vogue cover girl celebrated this year’s theme Rei Kawakubo / Commes des Garçons: Art of the In-Between in an embroidered sheer one-piece accented in metallic gold appliqués that cascade into a long, full train in the back.
She kept her beauty look simple with a low bun and gold headband because, as she wrote on Instagram, “Tonight, it’s all about the fashion. #MetGala”
She looked like such a longtime party goer that she even got the Met Gala social media cues down — she posted a getting-ready Instagram photo showing the “calm before the Met,” laying on the floor surrounded by her accessories for the night.
Despite being a two-time Vogue cover star (September 2010 and December 2002), this marks her very first time at fashion prom. But after seeing how amazing she looked on the carpet, we have a feeling this won’t be the last!
