Olivia Rodrigo's first BRIT Awards was a special night — she performed everyone's favorite hit, "Drivers License," finally met her ultimate idol Taylor Swift, and did it all wearing gorgeous custom Dior. While she walked the red carpet in an adorable neon green tulle dress, for her performance, she did a total 180 and entered the stage in a dramatic red gown — a departure from her usual playful style. The flowy Dior number, which London-based stylist Anna Hughes-Chamberlain helped create with the designer, was the perfect complement to Olivia's emotional, soulful voice. And can we talk about those incredible sleeves?
But the dramatics didn't stop there — under the sheer gown, Olivia was actually wearing a sparkly sequin bra top and matching shorts that glistened from all angles. We wonder if she was inspired by Dua Lipa's showstopping performance looks at the Grammys . . . Ahead, get a closer look at the "Deja Vu" singer's gorgeous ensemble.
