From streetwear to glamour—and back again: the Billie Eilish style saga

As her confidence grew with larger audiences and appearances at high-profile events, Eilish’s style remained true to her roots. She continued to favour oversized clothing, as seen here in a bold ensemble featuring a baggy t-shirt and Gucci shorts.

In 2019, Eilish fully embraced neon green—a colour many still associate with her today. This particular hue became a hallmark of her signature style, offering a striking contrast to her delicate singing voice. Fans came to expect this consistency, which underscored her ability to blend edginess with emotive artistry.

Eilish underwent a complete transformation during her Happier Than Ever era, leaving behind her streetwear look for a vintage-inspired aesthetic. With platinum blond hair and a softer, more romantic style, she showcased a new level of maturity—not just as a performer, but as an individual developing her own identity.

At the 2022 Met Gala, Eilish debuted jet-black hair and a stunning, custom-made satin corseted gown by Gucci. The look was both feminine and strikingly individualistic. Many praised her Gilded Age-inspired look as the only outfit “on theme” for the event, In America: An Anthology of Fashion.

At the world premiere of Barbie, Eilish paid homage to the theme in a pink ensemble. She went back to her tomboyish roots in Gucci menswear paired with brown Raf Simons shorts—a nod to her streetwear days.

Eilish appears to have balanced her love for oversized streetwear with a more refined approach, as seen in the two looks above. During her performance at the 96th Oscars, she donned an oversized Chanel blazer, while in Japan months later, she rocked a laid-back look consisting of a bandana and basketball shorts.
