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.
Ruth Negga made sure her appearance at the Oscars was not one to be forgotten, thanks to this lacy high-neck scarlet dress from Valentino with a romantic sweeping train and a Renaissance-style headband.
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.
Rooney Mara in lace Givenchy, a.k.a. the dress of our dreams. Her slicked back hair and staple red lip adds to the elegance of the gorgeous sheer number.
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.
Pike looks like a statuette herself in scarlet Givenchy Haute Couture, perhaps playing off her unforgettable bloody role in the previous year's Gone Girl.
Have you seen a chicer pregnant woman than Kerry Washington at the 2014 Oscars in this strapless Jason Wu dress? Pregnancy glow is real.
The then-newcomer stunned in a beautiful aquamarine custom Prada gown with a Fred Leighton headband that landed her on many best-dressed lists in 2014.
The giant tiered dress that caused the staircase-trip-seen-'round-the-world was a gorgeous haute couture gown by Dior.
Giselle from Enchanted but make it fashun. Adams wowed in an Oscar de la Renta dress with an ethereal frothy train that she helped envision with the designer.
It doesn't get much better than Cameron Diaz in Gucci.
Acting icon and epic speech-giver, Meryl mimicked an Oscar statuette (in her signature red carpet style: floor-length dress and plunging neckline) with this gold lamé Lanvin gown.
The Versace look that sparked its own Twitter account (@AngiesRightLeg) was the talk of Tinsel Town in 2012. Many saw it as a return to her cheeky younger red carpet image. It's definitely one way to ensure that your all-black dress is anything but boring.
Talk about sheer (!). This simple yet elegant Chanel gown on Michelle Williams is equal parts demure and sexy.
This aubergine gown by Rodarte was a double-header: a nod to the designer's role in her Oscar-winning movie Black Swan and a beautiful, enviably wearable maternity dress.
The year Mila Kunis wasn't even up for any awards (she was presenting), but probably crashed Pinterest with her appearance on the carpet this lavender Elie Saab gown.
Blanchett, a five-time Oscar nominee at this point, caused a stir in this Givenchy Couture pleated lilac gown encrusted with pearls.
The stunning Oscar winner for The Blind Side exuded glamour in this floor-length metallic Marchesa gown and perfect pink lip.
Katherine Heigl is the epitome of Old Hollywood in this one-shoulder red Escada gown, which she wore during her Grey's Anatomy days.
The mermaid dress is tough to nail without looking like a prom dress gone wrong, but when yours is a couture piece designed by Jean Paul Gaultier—covered with intricate scale embroidery—you're in a whole 'nother category.
