On Sunday, Pike arrived in Palm Springs, Calif., for the awards ceremony in a black and white pleated skirt by Proenza Schouler with a simple, black, long-sleeved knit top. She completed the look with black Brian Atwood sandals. The Gone Girl actress wore her hair in a sleek, low ponytail.

At the Creative Impact Awards, Pike was honored with the breakthrough performance award for playing Amy Dunne in David Fincher’s adaptation of Gillian Flynn’s bestselling novel Gone Girl.

“The breakthrough award makes you feel like you have surprised people, or people have seen your work in a different light which is all you ever want to do as an actor,” Pike told Us Weekly.

Pike is also nominated for Best Actress for the upcoming Golden Globes for playing the wife who elaborately frames her husband Nick Dunne – played by Ben Affleck – for her murder in Gone Girl. She’ll be competing against Reese Witherspoon (Wild), Julianne Moore (Still Alice), Felicity Jones (The Theory Of Everything) and Jennifer Aniston (Cake).
