7. Billie Eilish: In America: A Lexicon of Fashion, 2021
After showcasing her new blonde transformation in British Vogue a few months earlier, Billie Eilish arrival at the Met Gala in 2021 cemented her transformation from androgynous style icon to A-list pin-up. The theme of In America: A Lexicon of Fashion allowed the singer to pay a tribute to Old Hollywood glamour and her blush pink gown, designed by Oscar de la Renta, was inspired by the dress Marilyn Monroe wore to the Oscars in 1951. The feather-light tulle layers, combined with the voluminous style meant Billie was truly the belle of the ball.
8. Rihanna: China Through the Looking Glass, 2015
Rihanna brings her full style game to the Met Gala, and while all her outfits deserve to be awarded best in show, the cape-come-gown she wore in 2015 is arguably her finest fashion moment. Most people would keep the rest of their outfit relatively simple, but this is Rihanna, so she went large with a headpiece and necklace, which gave the whole look a very regal air.
