The Tamesis
Sienna Miller has long been a master of bohemian style. Her love for a romantic, free-spirited fashion aesthetic dates back to the 2000s, when she became known for strolling through music festivals like Coachella and Glastonbury in Chloé studded boots and vintage vests.
Even two decades later (today is her 44th birthday), Miller remains a fan of bohemian staples like ruffles, lace and maxi skirts, and her love of the whimsical came at a perfect time. This year, brands like Chloé and Valentino are leaning towards ruffles, and no one pulls off the modern bohemian look better than she does.
The American-British star has been reviving the look over the past year. It all started when Miller attended designer Chemena Kamali’s Fall 2024 Chloé debut, largely thanks to her rekindling the bohemian trend. Miller appeared front row wearing a black leather bomber jacket and white silk lace skirt from the brand. “This is the most beautiful show I’ve seen in a long time,” Miller told Fashion then. “It was like my dream wardrobe was walking past me.” That’s no surprise: The lace maxi dress and flowy fabrics seemed straight out of her 2000s wardrobe.
Once the fashion world fell in love with the look again, it didn’t take long for Miller to recapture the earlier trend. Since then, she has been on almost every red carpet – whether it was at the Met Gala or in promotions horizon– She continued this look, doubling down on Chloé’s elegant, soft and feminine design.

Take, for example, her appearance at the 2024 Met Gala, when she graced the steps of the Met in a white lace gown from the brand—a heavenly structure. Or when she attended the closing ceremony of the Venice Film Festival, wearing a sheer white lace dress paired with leather thigh-high boots and an oversized Chloé belt. On anyone else, this straight-from-the-runway look might feel straightforward, even lazy, but on Miller, it seemed entirely appropriate. She would wear something like this on a normal Tuesday.
Miller’s love of bohemian style extends to everyday pieces, too. For the Spring 2025 Chloé show, she chose a soft blue draped jacket and pink high-waisted trousers. She also appeared at the 2025 Fashion Awards in London wearing a gauzy white tulle gown by Givenchy by Sarah Burton. Dressed up or down, Miller perfectly captures the essence of bohemian dressing—i.e. no way It looks like you’re trying too hard. This skill is why she’ll forever be the queen of bohemian style, a trend we predict will continue into 2026.
