Isabelle Huppert, nominated for best actress for Elle showed her typically refined style in a long-sleeved silver Armani Prive gown, while Ruth Negga, also nominated in the same category for Loving, chose a lacy Valentino in the fashion house's signature vibrant red.

Negga and other attendees like model Karlie Kloss added a blue ribbon to their gowns and tuxedos to show support for the American Civil Liberties Union, an organization that worked to get President Donald Trump's travel ban blocked in courts.

Also sporting a blue ribbon was Lin Manuel Miranda, best known for Broadway's Hamilton. He had his mother on his arm as his date and noted proudly that he bought his tuxedo in Yonkers, New York, at the same shop where he bought his high school prom tux years ago.
