Irish actress Ruth Negga dazzled in a custom Valentino gown at her first Academy Awards.
The Limerick native (36) solidified her budding style icon status in the Victorian-style high neck gown, accessorising with a ruby hairband by the French fashion house, whose pieces she has championed throughout a chaotic awards season.
Most notably, however, Ruth, wore an ACLU (American Civil Liberties Union) blue ribbon, indicative of a politically charged night to come at the Dolby Theatre for the 89th Academy Awards.
She was nominated in the Best Actress category for her turn as civil rights campaigner Mildred Loving in Loving, while La La Land actress Emma Stone took home the award.

Also in the Best Actress category was Natalie Portman, Isabelle Huppert and Meryl Streep.
Ruth was joined by her boyfriend of six years, actor Dominic Cooper inside the ceremony, as the couple opted not to walk the red carpet together in order to detract from the growing public interest in their relationship. The couple also attended the Vanity Fair Oscars After Party together.
