19 Best Dressed Stars at the 2017 Oscars

The Hidden Figures star slayed in a custom off-the-shoulder navy velvet gown by Alberta Ferretti, which she paired with Nirav Modi jewels. Her diamond choker, black clutch and strappy heels were the perfect finishing touches.

Golden goddess! The La La Land star dazzled in a classy, custom-designed Givenchy Haute Couture dress by Riccardo Tisci, which she accessorized with platinum and 18k gold Tiffany & Co. earrings. Her beauty look, which consisted of big, bouncy curls and a bold red lip, oozed old Hollywood glamour.

The 16-year-old actress, who voices Moana in the Oscar-nominated Disney film, looked like a real-life princess at her first-ever Oscars. She wore a strapless white Rubin Singer dress, which she paired with stunning silver-and-gold jewelry.

The Edge of Seventeen star also gave us major princess vibes, stepping out to the red carpet in a dreamy floor-length Ralph & Russo couture gown that featured a sheer overlay and metallic, pastel-colored flowers. She completed her look with a dramatic smokey eye, light pink pout, elegant updo and diamond stud earrings.

Classic beauty! The Scream Queens star stunned in a spaghetti strap Armani Privé number, which featured cream crystal embellishments, a lacy bodice and two-tiered skirt. The red-headed beauty opted for loose, brushed-out curls, dangly earrings and a bright red pout.

Once again, the model shut it down on the red carpet, wearing a sparkly Zuhair Murad couture dress, strappy gold stilettos and a shiny clutch. And even though her husband, John Legend, admitted to stepping on her frock a few times while chatting with ET, it remained impeccable throughout the rest of the night.

Very much on trend with all the white we saw on the Oscars red carpet, the 24-year-old model stole the show in a full-length Stella McCartney number, complete with an asymmetrical cape. The blonde beauty upped the glamour with a silver-and-white chain purse, lush curls and a choker and earrings by Nirav Modi.

Rocking a fully embellished gold KaufmanFranco gown and Tiffany & Co. jewelry, The Book of Love star looked like a real-life version of an Oscars statuette. She kept full focus on her stunning frock by sporting minimal makeup and a sophisticated updo, which featured a middle part.

The Hidden Figures star rocked the night's most out-there gown, but pulled it off flawlessly! "[It's] Elie Saab couture," she told ET on the red carpet. "Forever Mark on the fingers and ears. And I'm just so happy to be here."

"I'm an android and I have secret ways of getting in places smoothly," she added, joking about how she miraculously got into the car without snagging the stunning number.

Who says you can't recycle a pair of heels for the Oscars? The Hidden Figures star re-wore her favorite Christian Lacroix ankle-strap pumps on Sunday, opting for a black high-low Christian Dior Haute Couture dress, a Niwaka diamond necklace and voluminous updo to complete her chic look.

The Room star, chic in a strapless black velvet Oscar de la Renta gown, wore a similar ensemble to Dunst. She styled her dress with black Aquazzura heels, Neil Lane jewelry, a red lip and messy half-up, half-down hairstyle.

When in doubt, wear red! The Loving star rocked a red-hot Valentino number while making a political statement with her blue ACLU (American Civil Liberties Union) ribbon positioned on the left side of her dress.

The Jason Bourne star also made a red carpet statement, stepping out in a black Louis Vuitton dress and sandals. She kept the rest of her look simple with a stunning statement necklace and messy updo.

Nothing Scandal-ous about this look! The 45-year-old actress wowed in a white Georges Chakra Couture gauzy dress, adding a pop of color with a pair of turquoise chandelier earrings.

Per usual, the Lion star pulled out all the stops for her red carpet look, this time dressed in a champagne-colored Armani Prive gown, which featured intricate beading. She accessorized with a vintage OMEGA museum timepiece and more than 119 carats of Harry Winston jewels.

The Moonlight star attended the ceremony just four days after welcoming his first child, a daughter, with wife Amatus Sami-Karim, and was all smiles while posing for photographers. He looked exuberant in his all-black ensemble -- which consisted of a square print mohair, tuxedo, satin bow tie and pocket square -- by Ermenegildo Zegna Couture.

And this is how you wear a tux! The Captain America: Civil War star looked as handsome as ever, sporting some scruff and a Salvatore Ferragamo suit, which featured a black bow tie and pocket square.

The actor, who voices Maui in Disney's Moana, rocked a Robert Mata Designs ensemble, which consisted of a black bow tie, velour jacket and black dress pants.

Classy as they come! While a number of men donned classic black tuxedos and bow ties on the red carpet, no one did it better than the Hidden Figures star, who was dressed in Giorgio Armani.
