The 40-year-old Mad Max: Fury Road star dazzled in a jaw-dropping fire red Dior dress, accentuating her plunging neckline with $3.7 million worth of Harry Winston diamonds.

And the back of her dress wasn't half bad either.

It's safe to say, at 40, Charlize has never looked better.

The 25-year-old Suicide Squad star shined in a bold gold Tom Ford sequin dress, looking like a total goddess.

The 21-year-old Brooklyn star, who was up for Best Actress, hit it out of the park in a gorgeous green sequin Calvin Klein Collection gown, which she paired with matching Chopard jewelry.

The back of the dress turned heads as well, thanks to its almost completely open design.

While the neckline of Rachel McAdams' silky green August Getty dress is technically a halter, an honorable mention has to go to the 37-year-old Spotlight star, who stunned many in a daring, totally backless design, which also featured a thigh-high slit.

Has Rachel ever looked sexier than in this plunging back design?!

Jennifer Lawrence:

The 25-year-old Joy star, who was also up for Best Actress, looked amazing and stayed true to her style in a sheer lace Dior creation. Simple makeup and an unfussy bob completed her elegant look.
