The Spencer actress, 31, arrived on the famous red carpet staircase in head-to-toe Chanel: a metallic ruffled pink jacket over a lace blouse and tuxedo pants. But once she got inside and headed to her dinner table, she decided to slip off the jacket, and ended up showing more skin than intended. "So I go to the Met ball and there's a new set of kids at the Chanel table. There was a beautiful young tennis player [Emma Raducanu] and a young actress [from the Gossip Girl remake, Whitney Peak]," Stewart tells PEOPLE in this week's issue on newsstands Friday. "I'm talking to them, saying, 'Welcome, I've done this a couple times,' and they look like I'm scaring them. I look down, and literally my [nipple] is in their faces. I was like, 'Okay, sorry, I'll put that away now,'" she says. The Met Gala 2021 Red Carpet Looks You Must See Stewart jokingly adds: "They're like, 'Who is this crazy old actress at the Met Ball?' This is going to be a story for them when they're older." The actress has been a longtime staple at the Chanel table, having first been tapped by the brand as the face of Chanel's 2013-2014 Métiers d'Arts ad campaign in 2013.

While she's always on-hand for Chanel's runway shows, the next major fashion moment fans will see from Stewart is when dons a replica of Princess Diana's iconic wedding dress in her new film, Spencer (out now). "When we put that dress on, it is embedded in a montage that kind of flashed her life before you. Even though the movie takes place over a three-day period and even though I play her as a speculatively 29-, 30-year-old person, we still wanted to give a taste of the scope of her life," Stewart told Entertainment Tonight. "Kind of touch on every part, even if it was in kind of lyrical dance. And the wedding dress is embedded in that montage and putting that on was a spooky day."
