Celebrities embraced workwear and menswear looks at Oscars events, from Zendaya to Kristen Stewart

Zendaya channeled Sharon Stone's 1998 Oscars ensemble with crisp white shirting.

Zendaya took a page from Sharon Stone's style guide and put a twist on a classic white button-down. The actress paired the cropped shirt with a sparkly silver skirt from Valentino.

The "Dune" star rocked a stunning suit to the Vanity Fair Oscars after-party.

According to Glamour, Zendaya's double-breasted suit is from Sportmax. She paired it with a leather tie, magenta shirt, and Bulgari jewelry.

Uma Thurman also wore a striking all-silk ensemble on the red carpet.

The actress paid tribute to her "Pulp Fiction" character Mia Wallace with a black floor-length skirt by Bottega Veneta and a crisp white skirt.

Hannah Einbinder rocked an off-white tuxedo look to the Vanity Fair after-party.

Einbinder's blunt bob allowed her monochrome ensemble and tailoring to pop.

Lady Gaga wore a sparkling take on the tuxedo while on stage with Liza Minnelli.

Harper's Bazaar reports that Lady Gaga's tuxedo is actually a Ralph Lauren jumpsuit. She wore classic accessories with the look, which included black pumps and a bow tie.

Never one to shy away from a great suit, Lena Waithe brought neutrals to the red carpet.

Waithe also wore a suit to the Vanity Fair Oscars after-party, but her brown-and-black ensemble, turtleneck, and patent shoes stood out.

Kelly Marie Tran matched with Mexican filmmaker Carlos Lopez Estrada in an emerald tuxedo jacket and black shirting.

The actress and filmmaker paired their fitted jackets with matching green skirts.

Daniella Haim popped with an oversized tuxedo jacket over a black bra.

The musician, joined by her sisters Esta and Alana (who starred in the Oscar-nominated film "Licorice Pizza") balanced the all-black look by showing some skin.

Best actress nominee Kristen Stewart and her fiancée Dylan Meyer both wore spins on menswear.

Stewart's custom Chanel suit and billowing shirt stood out as one of the most daring looks of the night. Meyer also opted for the open-shirt look but wore it with a full-length floral suit.

Maggie Gyllenhaal opted for all-white at the Vanity Fair after-party as well — with a twist.

With stunning beading and a snatched waistline, Gyllenhaal served one of the most underrated looks of the night.

Although Tessa Thompson's bold collar catches the eye, it's balanced with monochromatic tailoring.

Like Stewart, Thompson brought shorts and heels to Oscars night. Her slicked-back hair and minimal accessories didn't overwhelm the black collar.

Hayley Kiyoko served stunning simplicity at Elton John's Oscars viewing party.

The look was so simple it didn't even need a shirt. Kiyoko's all-black suit made an impression.

Wanda Sykes looked sharp in a bright white tuxedo and pointed-toe shoes.

Sykes didn't disappoint with structured shoulder, perfect pants, and minimal accessorizing.
