Stars are mixing high fashion with some advocacy on the Oscars red carpet.

Several top nominees are sporting blue ribbons supporting the American Civil Liberties Union, including best actress nominee Ruth Negga and best original song nominee Lin-Manuel Miranda.

Miranda brought his mother to the Oscars, and she also prominently displayed the ribbon. The ACLU is among the groups suing over a travel ban imposed by President Donald Trump’s administration that has been placed on hold by federal courts.

Director Barry Jenkins planned to wear one, and realized in the middle of a red carpet interview that he had lost it.

Jenkins, who is nominated for best director for “Moonlight,” says he does not yet know what he would say if he wins an Oscar Sunday. He says, “I think art is inherently political,” and he supports any artists who speak out about politics at the awards show.

Anthony D. Romero, executive director of the ACLU told Page Six in a statement, “The support of the entertainment community for the ACLU’s work protecting our civil liberties has been nothing short of spectacular, and tonight is no exception. Their voices are crucial in our fight to defend the Constitution and its promise of equality and justice for everyone in our country — no matter who they are and where they come from.”

Best actor nominee Casey Affleck also wore the ribbon at Saturday’s Independent Spirit Awards, where he won the award for best male lead.
