Last night, Vogue threw its annual Met Gala ball at New York’s Metropolitan Museum Of Art, in which tons of celebrities get together to wear deeply silly clothes in celebration of the entire idea of fashion. Or something. I honestly don’t really understand it. This year, the theme was Manus x Machina: Fashion in an Age of Technology, which meant a lot of people dressed in vaguely robot-influenced outfits. Kanye West wore ripped-up jeans, a glittery disco-ball jacket, and blue-grey contact lenses. Zayn Malik wore robot arms. It was really something. The Weeknd performed at the event, bringing out Nas to do a new verse over his Kanye-produced Beauty Behind The Madness single “Tell Your Friends.” Below, watch that performance and marvel at some of last night’s looks.
