The star of the movie "Barbie" justified the title with a loose and light aspect as befits the atmosphere of the show. Ruby, an ambassador for the French brand, arrived in a minimalist black triangle bra, matched by high pedalphone jeans in light blue.
Also present at the event were Sophia Richie, Elle Fanning, Camila Moreno and Kristin Stewart in a black and white tweed suit and gourmet necklace with the Chanel logo. For more pictures from the Met Gala click here.
