Kate Mara took her hair to new heights when she walked the 2014 Golden Globes red carpet on Sunday!

The "House of Cards" star, who days ago just debuted her new bright blond hair, showed off a a goth-meets-glam look that was one-of-a-kind.

The 30-year-old wore a silver floor-length J. Mendel gown that revealed a generous amount of cleavage and featured space-age winged shoulders and a draped middle that gathered at the centre of her body to reveal an extra pleated layer underneath.

Aside from the eye-popping dress, the former "American Horror Story" actress stood out because of her gravity-defying hair, which was teased beyond recognition into an updo super thick a la Gretchen Wieners. (It's full of secrets!)

Mara, sister of "The Girl With the Dragon Tattoo" star Rooney Mara, is not nominated this year (although we love her as spunky Washington reporter Zoe), she showed up at the ceremony to support her "House of Cards" co-stars including Kevin Spacey and Robin Wright, who won the award for Best Actress in a TV Drama (and just confirmed her engagement to actor Ben Foster).

What do you think of Kate's vampy look?

They're all so beautiful:
