The 90th Annual Academy Awards was full of fierce fashion.
From sparkly gowns to sophisticated suits, Hollywood's most stylish men and women dressed to impress while stepping out to the Oscars red carpet at the Dolby Theatre in Los Angeles on Sunday.
Now, ET's breaking down our 18 favorite looks from the grand finale of awards shows!
1. Jennifer Lawrence
Glam goddess! The Red Sparrow star topped our Best Dressed list for obvious reasons -- the sparkly Christian Dior dress, the effortless waves and that ultra-dramatic smokey eye. Killin' it, J. Law!
2. Gal Gadot
Seemingly taking a cue from Lawrence, the Wonder Woman star also opted for head-to-toe sparkles, turning heads in a silver Givenchy dress with a diamond statement necklace from Tiffany & Co. and a berry lip.
3. Margot Robbie
The I, Tonya star wore one of the most intricate looks on Sunday's red carpet, a Chanel Haute Couture dress custom-made by Karl Lagerfeld. The gown required 550 hours of work and seven people to complete it ahead of the awards show.
4. Jennifer Garner
Babe in blue! The brunette beauty was a vision on the red carpet, flaunting her fit figure in a royal blue Atelier Versace gown. She topped off the flowy, princess-like piece with matching open-toe stilettos, dangly earrings and a bombshell blowout.
When it comes to red carpet fashion, the former Disney star never fails to impress us. Z turned heads in a chocolate brown, off-the-shoulder chiffon frock by Giambattista Valli Couture. She completed the chic look with a classy top knot, jewelry by Bulgari and Brian Atwood sandals.
6. Timothée Chalamet
The Call Me by Your Name Oscar nominee stood out from the crowd in an all-white custom Berluti suit with a crisp button-up and matching bow tie. The 22-year-old actor added his own personal flair to the ensemble by wearing black boots.
7. Saoirse Ronan
Pretty in pink! The Lady Bird star opted for a simple, but elegant look for the awards show, consisting of a strapless Calvin Klein dress with matching pumps. She kept the rest of her look feminine with a trendy short 'do and minimal accessories.
8. Nicole Kidman
Like Garner, the Big Little Lies star also opted for blue, but in a much darker hue. The blonde beauty styled her sculptural Armani Privé gown with sleek, straight hair, strappy Louboutin heels and Harry Winston jewels.
9. Mary J. Blige
The Oscar nominee and performer made a glamorous statement in an off-the-shoulder Atelier Versace creation that perfectly showed off her curves. She accessorized her winning look with stunning Forevermark jewelry.
10. Jordan Peele
Looking extra dapper was the Get Out director, clad in a fitted white suit jacket, button-up and a black bow tie and trousers. His peppered beard was an added bonus!
11. Allison Janney
Va-va-voom! The first-time Oscar winner knocked it out of the park in a striking custom Reem Acra design with a plunging neckline and angel sleeves.
12. Laura Dern
The Big Little Lies star wore a Calvin Klein by Appointment white silk crepe dress with a draped tie at the shoulder. She added a touch of shine with bordeaux asymmetrical crystal sandals and a sterling silver evening bag.
13. Allison Williams
Pure perfection! Giving off major princess vibes, the Get Out star shimmered in a blush Armani Privé ballgown that featured a rhinestone and crystal embroidered bodice and a full crinoline swing skirt.
14. Lupita Nyong'o
Fierce and fabulous! The Black Panther star turned heads in a black-and-gold custom Atelier Versace dress, which she paired with a Versace clutch handbag, Alexandre Birman heels and Niwaka fine jewelry.
15. Jane Fonda
The Grace and Frankie star brought her A-game to the carpet once again, slaying in an all-white ensemble consisting of a Balmain dress, Chopard jewelry, Salvatore Ferragamo shoes and a Perrin Parris bag.
16. Lakeith Stanfield
Navy never looked so good! The Get Out actor looked slick in a custom-made blue silk tuxedo with black contrast peak lapel, tuxedo shirt and bow tie by Ermenegildo Zegna Couture.
17. Zoey Deutch
The fashionista channeled Old Hollywood in a dusty lilac, hand beaded, tiered Elie Saab Haute Couture gown, which she paired with Stuart Weitzman shoes and Tiffany & Co. jewels.
18. Armie Hammer
The Call Me by Your Name stud always looks debonair, but his Oscars look took it to a whole new level. Hammer arrived in a Giorgio Armani Made to Measure burgundy velvet suit with a classic white shirt and a black bow tie.
