Billie Eilish Wears 1965 'Poodle Parade' Barbie-Inspired Look for Her 2024 Grammys Performance

Pink headscarf! Checkered cardigan! The star matched a look from Barbie's 1960s era

Billie Eilish channeled her inner Barbie girl again, this time in a vintage-inspired look from the 1960s.

On Sunday, the singer-songwriter, 22, took the stage at the 66th annual Grammy Awards to sing her song “What Was I Made For?” dressed head-to-toe in an iconic outfit almost identical to the 1965 limited-edition Poodle Parade Barbie.

For the look, Eilish – who's one of the youngest artists to ever be nominated for a Grammy — wore a satin pink headscarf over her red hair, a 1960s-inspired green dress over a pink shirt and a green-and-white plaid cardigan.

On the red carpet, Eilish also paid tribute to Barbie. She wore a vintage Barbie-themed bomber jacket from Chrome Hearts that was reworked specifically for her.

The Grammy-winner's black jacket featured light pink sleeves, silver heart-shaped buttons and "Barbie" embroidered in pink on the front. Eilish paired her jacket with a casual, untucked white button down shirt and black dress pants.

Meanwhile, her brother and co-writer Finneas, 26, matched his sister in a head-to-toe black outfit. The Grammy-nominee wore a black button down, black dress pants and a silver necklace.

Already a seven-time Grammy winner before Sunday’s ceremony, Eilish won best song written for visual media for "What Was I Made For?" before hitting the red carpet with Finneas.

“We put one song out this whole year. And did not think it would get — maybe one, even, let alone six. Which is really, really crazy,” she told Amanda Kloots and Alina Vission at the GRAMMY Live! from the Red Carpet pre-show.

“This was supposed to be an off year. Didn’t put an album out, didn’t do anything. We really made one song and we were like, ‘Here you go.’ ”

She continued of the nominations, which include record of the year, song of the year, best pop solo performance, best song written for visual media, and best music video: “It's just insane. It's so surreal and amazing.”
