The 27-year-old actress hit the red carpet in a striking black dress with a shiny gold breastplate.

The unique dress highlighted her stunning figure as she posed for photos ahead of the screening at the historic Egyptian Theater.

Her chic jaw-length hair was worn in soft curls that framed her heart-shaped face.

Steinfeld – who voices “Vi” in the series based on the popular video game League Of Legends – rocked a moody black manicure.

As for jewelry, she kept it simple with a small pair of gold hoop earrings and a gold ring on her right hand.

Steinfeld wore sultry winged eyeliner and a bright peach shade on her cheeks.

Her makeup artist completed the soft, glamorous look with a nude lip and a light dusting of bronzer to give Steinfeld's skin a sun-kissed glow.

The actress happily stopped on the red carpet to take selfies and sign autographs for fans.

She was joined at the premiere by her stunning co-star Ella Purnell, 28.

Purnell – who became a household name after starring in the popular series Fallout – looked gorgeous in a red faux leather suit.

It consisted of a buttoned top with puffed sleeves, a white lace collar and a pleated skirt.

The English actress, who voices “Jinx” in Arcane, wore her brunette locks in wavy braids and pinned a pair of silver hoop earrings to her ears.

To complete her red carpet look, Purnell slipped on a pair of black heels and a slim black belt with silver studs.

Abbott Elementary star Sheryl Lee Ralph looked phenomenal in a black patent trench coat over a busty corset top and a skin-tight pencil skirt.

Steinfel and Purnell posed for photos with several of their co-stars, including Toks Olagundoye, as well as the show's executive producer Christian Linke.

Arcane released its first season on Netflix in 2021 with nine episodes released weekly.

“Set in the utopian Piltover and the oppressed underground of Zaun, the story follows the origins of two legendary League of Legends champions and the force that will tear them apart,” reads the official IMDb synopsis.

In 2022, Arcane won the Emmy Award for Outstanding Animated Program.

The second season of the successful animated series will premiere exclusively on the streaming platform on November 9th.

Hailee's appearance at Wednesday's premiere in LA comes amid her romance with 28-year-old Buffalo Bills quarterback Josh Allen.

She and the NFL superstar made their romance Instagram official in June after dating for nearly a year.

The two first sparked dating rumors in May 2023 while out and about together in New York City.

In July this year, they seemingly confirmed their romance when they were spotted vacationing together in Mexico.

Since then, Hailee has supported Josh at several of his football games, including last month when she was spotted in the stands wearing vintage Buffalo Bills gear.

Steinfeld recently revealed that Allen almost jinxed their relationship with the Christmas present he bought her last year.

She revealed this in her newsletter, explaining how the Bills star bought her a knife for Christmas in 2023.

“I got this knife for Josh for Christmas last year because we like to cook together,” she said. “For Christmas he gave me… the same thing in a different color!”

“After we exchanged our knives, he told me that there is an old wives' tale: If you give your partner a knife, you have to pay for it, otherwise it means breaking off a relationship.” So we swapped quarters so that we wouldn't be like that had a bad omen.

“Anyway, oh my god, I love this knife!” I don't know much about a chef's knife, but it's just so beautiful and makes me feel official.”

The knife in question costs around $430 – chump change for Allen, who has a six-year, $258 million contract with the Bills.
