It's been a while since we've seen Rachel McAdams on an Oscars red carpet ! But she returned with bang in a look that's one to beat.

Clad in an August Getty Atelier emerald green dress, McAdams reclaims the statement gown with a simple neckline but an amazing train and slit. The gorgeous actress pairs her dress with a slicked back updo and neutral makeup.

McAdams is nominated for her first Academy Award this evening. She's up for Best Actress In A Supporting Role for the critically acclaimed film "Spotlight."
