When Billie Eilish stepped onto the 2025 Grammy Awards red carpet wearing a Prada sailor hat and an oversized V-neck jacket, the internet didn't just look—it argued. Some called it "fisherman chic." Others saw it as a retreat back into the baggy silhouettes that defined her early teens. Honestly, they’re both kinda right, but they’re also missing the bigger picture of how Billie uses the red carpet as a weapon for personal autonomy.
The Billie Eilish Red Carpet Formula
For a long time, the world tried to put her in a box. You probably remember the 2020 era: head-to-toe neon green and black Gucci, baggy enough to hide every curve. She told Vogue back then that it was a defense mechanism. If they can’t see you, they can't judge you. But then 2021 happened. The blonde hair. The Oscar de la Renta gown at the Met Gala that looked like a peach-colored cloud. People lost their minds.
What most people get wrong is thinking these are "phases." They aren't. Billie Eilish red carpet appearances are actually a masterclass in switching the narrative whenever the public gets too comfortable.
That 2024 "Barbie" Pivot
Look at the 2024 Oscars. While everyone else was wearing floor-length sequins, Billie showed up in a Chanel schoolgirl look. We’re talking a black blazer, a white button-down, and a tweed pencil skirt paired with white socks and Mary Janes. It was "corporate core" before that was even a TikTok trend.

It was a nod to her 2020 Oscars debut in white Chanel tweed, but updated for someone who had just swept awards season for "What Was I Made For?" She wore an Artists4Ceasefire pin on her lapel, reminding everyone that for her, the carpet isn't just about the fit—it’s about the message.
Sustainability Isn't Just a Buzzword
If you look closely at her history, Billie is low-key the queen of upcycling. At the 2022 Met Gala, she wore a custom Gucci corset gown that was made entirely of repurposed materials. Most stars want something "new-new." Billie wanted something old made new.
She did it again at the 2024 Grammys. That custom Chrome Hearts bomber jacket with the pink satin sleeves and "Barbie" embroidery? It was reworked from vintage pieces. She’s consistently showing that you can be the biggest pop star on the planet without contributing to the fast-fashion nightmare that usually haunts high-end events.
The 2025 Prada Era
Her most recent major appearance at the 2025 Grammys felt like a homecoming. The look was Prada, but the vibe was pure Billie.

- The Hat: A black Prada sailor cap that shadowed her eyes.
- The Shades: Small, oval Chrome Hearts sunglasses.
- The Fit: Wide-leg black trousers and a layered collared shirt.
It was minimal. It was dark. It was, as some critics noted, a "symphony of music and fashion" that mirrored the mood of her album HIT ME HARD AND SOFT. She wasn't trying to be the "pretty girl" the media demanded after her blonde era; she was just being Billie.
Why Her Red Carpet Choices Still Matter
Fashion critics often talk about "the transition" from baggy clothes to feminine gowns as if it were a linear path to "growing up." That’s a mistake. Billie's style is a circle. She moves between the Rick Owens capes of the 2022 Grammys and the gothic Simone Rocha lace of the 2023 Met Gala because she can.
She’s basically telling us that femininity isn't a costume you put on and leave on. It’s a tool. Sometimes she wants to look like a Gilded Age portrait (like her 2022 Met look inspired by John Singer Sargent's Madame Paul Poirson), and sometimes she wants to look like she just stepped off a skate deck.

Tips for Nailing the "Billie" Aesthetic
If you're trying to channel that energy without a Prada budget, it’s actually easier than you think. It's about contrast.
- Ditch the symmetry. Wear something oversized on top and structured on the bottom, or vice versa.
- Invest in eyewear. Billie is rarely seen on a carpet without sunglasses, even indoors. It adds that layer of "you can't fully see me" that she loves.
- Go vintage. Hit up thrift stores for blazers or old varsity jackets. The more "lived-in" it looks, the more authentic it feels.
- Socks matter. Whether it's the high white socks at the Oscars or the logo tights at the LACMA Gala, the feet are never an afterthought.
The real takeaway from years of watching Billie Eilish red carpet moments is that authenticity is more valuable than any "Best Dressed" list. She doesn't dress for the cameras; she dresses for herself, and that’s why we’re still talking about it.
To keep your own style evolving, start by picking one "rule" of fashion you hate—like mixing patterns or wearing baggy clothes to a formal event—and break it intentionally this week.
