The Oscars have forever been the fashion Olympics for Hollywood's brightest stars. Style chameleons like Cate Blanchett and Nicole Kidman regularly steal the show, while risky contenders like Björk still live in our hearts (and memes). Ahead of the biggest night in film and television, we're taking a look back at the most memorable outfits of Academy Awards past.
We can't stop staring at this royal blue Armani gown—complete with a corset, bow, and slit—on Nicole Kidman at the 2018 Oscars. It perfectly complements her skin tone, too.
Margot Robbie looked like an angel in this white Chanel gown, which she wore when she was nominated for her role in I, Tonya.
Tiffany Haddish's gorgeous gown was a tribute to the African country of Eritrea, where her father was from (he'd passed away the previous year). We're not crying, you're crying.
Once more for the people in the back: Viola. Davis. Is. Queen.
Eiza González brightened up the red carpet in a very yellow Ralph Lauren gown that shows less can be more.
Please observe the detailing on Janelle Monáe's fairytale Elie Saab Haute Couture gown. It was her first time at the Academy Awards, and she couldn't have nailed the outfit better.
Aniston presenting an award in Atelier Versace proves that black doesn't have to mean boring. The open leg, v-neck style has been popular recently among celebrities like Jennifer Lawrence.
We can't tell whether this geometric Ralph & Russo dress looks better from the back or the front. It's that gorgeous, and nobody could wear it as well as Chopra.

This va-va-voom Alberta Ferretti look on Taraji P. Henson is understated, but speaks volumes about her style, confidence, and killer body, as many Internet users pointed out.

Aaaaand she nails the landing! Cate Blanchett (can she do any wrong?) is a vision in this sea-foam feathered gown by Armani Privé.
McAdams chose a relatively understated look from August Getty (no over-zealous beading or abundant tulle), but she's subtly pulling off other Oscars staples, too—thigh-high slit, low back, and sweeping train—in a very refreshing emerald hue.
Okay, so this outfit was technically from the after party, not the red carpet, but it felt impossible to leave out this stunning long-sleeve Louis Vuitton gown Gomez wore in 2015.
One reason why we're thrilled Emma Stone ended up landing the role in La La Land: her auburn hair naturally vibes with the colorful frocks she chooses for red carpet events. Here, she's wearing a risk-taking Elie Saab gown in mustard yellow that 100-percent pays off.
