Billie Eilish keeps her schoolgirl streak going in sweater vest on the SAG Awards 2024 red carpet

School’s always in session for Billie Eilish.

The “Happier Than Ever” singer, 22, proved to be the queen of quirky-cool style once again on Saturday night, walking the SAG Awards 2024 red carPet in a white dress shirt and tie with a sweater vest.

Eilish paired her sheer sweater vest with black pants as she posed for the cameras, wearing her hair pulled up in a loose updo.

The Grammy winner — who is set to present at the awards show and told E!’s Laverne Cox that she wanted to look “presentable” — has rocked her fair share of statement-making ensembles over the past few months.

She also wore a sweater vest (along with baggy black pants) to the People’s Choice Awards last week, and back in January, the “What Was I Made For?” singer showed up at the Golden Globes wearing a school-inspired outfit from Willy Chavarria, complete with an oversized blazer, khaki skirt and a striped button-down.

Earlier this month, Eilish opted to pay homage to “Barbie” at the Grammys, first with a black and pink varsity jacket that featured the doll’s logo, then with a retro shift dress and gingham jacket as she took the stage.

Performing her hit song from the film, she looked near-identical to 1965’s Poodle Parade Barbie, even including the headscarf and sunglasses as part of her outfit.

While the singer won’t have the opportunity to take home a trophy this time around, the “Barbie” movie is up for four SAG awards in total.

The film has the possibility of winning best cast and outstanding performance by a stunt ensemble, while both Margot Robbie and Ryan Gosling received nominations for their memorable roles.

Still, Eilish’s stylish awards season isn’t over. In March, she’ll attend the Oscars, where “What Was I Made For?” is nominated for best original song.

Will she switch things up for the much-anticipated night, or continue to keep it casual with oversized clothing? We’ll have to wait and see.
