See what the Academy Award nominees, including Brie Larson and Cate Blanchett, wore as they hit the blue carpet less than 24 hours before Sunday's big shebang.

With T minus 18 hours to go until the Oscars glam prep begins, Academy Award nominees Rooney, Mara, Cate Blanchett, Brie Larson and Rachel McAdams stepped out at the Indie Spirit Awards in their daytime best.

The more casual show, which always precedes Hollywood’s biggest night, is like a style pregame for the nominees doing back-to-back carpet duty, and the the ladies certainly didn’t disappoint.

Mara arrived in a tea-length sleeveless dress, which she paired with an edgy updo, strappy black sandals and minimalist silver rings. Her best supporting actress competition, Rachel McAdams, arrived in a contrasting summer ensemble by Solace London with a reverse high-low skirt. The Spotlight star matched her lip color with her baby pink belt and opted for a half-up, half-down hairstyle.

Oscars best actress nominees Blanchett and Larson also hit the blue carpet in summer-ready ensembles. Larson rocked a bright red lip that popped against her blue two-piece Chanel ensemble, while Blanchett kept it cool in an embroidered floor-length Gucci number whose foliage print definitely reminded us that spring is just around the corner. She topped off the ensemble with matching shades for Santa Monica-friendly look.
