Ruth Negga showed up to the Oscars red carpet [1] in a stunning long-sleeved red lace dress by Valentino. The actress accessorized her sophisticated look with Irene Neuwirth crown and earrings, covered in Gemfields rubies.

The most notable accessory, however, was a small blue ribbon that Ruth attached to her dress. The ribbon represents solidarity with the American Civil Liberties Union. Lin-Manuel Miranda [2] and Casey Affleck [3] have also been spotted wearing the ribbons on award season red carpets, and you can bet you'll see plenty more tonight [4].

Ruth is up for best actress [5] for her performance in Loving, a historical drama about an interracial couple who were the plaintiffs in the Supreme Court case Loving v. Virginia, which made interracial marriage legal on a federal level.
