The Academy Awards, also known as the biggest night in Hollywood, are quickly approaching, and it's safe to say that we here at the InStyle offices are getting just a teensy bit antsy. From the red carpet to the awards show to the after parties, there's no doubt the night is going to be a memorable one. In anticipation of the impending event, we're taking a look back at the incomparable style of the best actress nominees. Keep reading to see why:

The gorgeous red head (top), who has so far swept awards season for her role in Still Alice, is a red carpet favorite of ours. Despite the fact that she's an awards season red carpet veteran, Moore always manages to keep her look fresh -- probably because she's not afraid to take a risk.

She's America's Sweetheart no more. From her gritty role in Wild to the non-stop parade of sexy ensembles she's been hitting the red carpet in, it's safe to say that Witherspoon's style, which once could've been described as sweet-as-sugar, has done a complete 180.

Although the Gone Girl actress is a relative awards season rookie, she's already cementing herself as a style star. From her eye-catching white cutout gown at the Golden Globes to her floral-appliquéd Dior frock at the SAGs (above), Pike has our attention.

The French actress, who hadn't received any award nominations for her role in Two Days, One Night prior to the Oscars, shocked the country when it was announced she was a nominee. We think it's safe to say she'll shock us all again when she walks the red carpet on Feb 22. Although she favors Dior, the actress is never one to shy away from a statement-making gown.

Jones, another awards circuit newbie, has impressed us from the get-go. Whether it's her awe-inspiring performance in The Theory of Everything, her humble red carpet interview personality, or her envy-inducing style, it's safe to say that the actress isn't going anywhere.
