Billie Eilish [1] showed up for her cochair duties [2] at the 2021 Met Gala [3] in a peach, floor-sweeping Oscar de la Renta gown with a corseted bodice and tulle train. The off-the-shoulder design was complemented by 30 pieces of Cartier jewellery — the most anyone has ever worn on the red carpet, according to E!. "This is the first thing I've ever done in this realm before. I'm shivering and shaking," Billie said upon speaking to the network about her glamorous moment.

Billie reportedly used her influence and platform to ask the Oscar de la Renta team to stop using fur when she made the agreement to work with the American fashion house for the special event. While her hairstyle might gives off Marilyn Monroe vibes, her beauty is undeniably Billie, and everything about her demeanour on the Met steps speaks to the personality her fans continue to love and cheer for.
