But one Vogue cover girl who’s never walked the red carpet just made her big debut in the most dramatic way possible. Halle Berry arrived wearing a sheer body-hugging halter jumpsuit with over-the-top tiered train that left our jaws on the floor.

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 and accessorized with Atelier Swarovski earrings.

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!

What do you think of her red carpet debut?
