Kim Kardashian stepped out onto the 2021 Met Gala steps in a daring blacked-out ensemble.

The outfit was designed by Balenciaga creative director Demna Gvasalia and featured black leggings that connected to black heels, a black tunic with bell sleeves, black gloves, a face obscuring headpiece, and a long black train.

Kardashian, 40, attended the star-studded fashion event with Gvasalia as her date.

The Met Gala, which raises money for the museum's Costume Institute, was pushed last year from its traditional May berth and morphed this year into a two-part affair.

It coincides with the opening of "In America: A Lexicon of Fashion," the first of a two-part exhibition at the Met's Anna Wintour Costume Center.

The official dress code this year is "American Independence" and the night's co-chairs include singer Billie Eilish, actor Timothée Chalamet, poet Amanda Gorman, and tennis champion Naomi Osaka.

Organizers invited 400 guests, or about a third the number that usually attend. They must be vaccinated and wear masks inside the museum.
