Some celebrities make bold fashion choices on the red carpet, but Brie Larson could be making a statement of a different kind at the 2017 Academy Awards.

The Oscar-winning actress, previously confirmed as one of the ceremony’s presenters, hinted at some of the accessories she might wear to the prestigious event.

“Proud to support @ACLU, @PPFA, and @glaad all day, everyday. #istandwithpp #standwithaclu #weresist,” she tweeted Sunday alongside a photo of several pins representing Planned Parenthood, the ACLU, and GLAAD, later adding: “Still can’t believe it. Excited for tonight!!!”

Since winning her first Academy Award last year for her performance in Lenny Abrahamson’s Room, Larson has been a vocal supporter of philanthropic and humanitarian causes, particularly in recent months. Via Twitter, she has called for peace and unity amid growing political turmoil in the United States, and has championed issues pertaining to minority rights — including causes relating to the gay and transgender communities — in the past.

Watch the 89th Academy Awards Sunday at 8:30 p.m. ET on ABC.
