Everyone, meet the best dressed person of the night: Rachel McAdams.
The Spotlight star, who is up for Best Supporting Actress, slayed in an emerald August Getty Atelier gown that elegantly, beautifully revealed her leg as well.
And leg for dayssss:
Plus a stunning long train to boot!
We also love that in addition to a sexy high slit, her dress featured a high-neck but exposes her back.
