Nostalgic for Boho Style? So Is Sienna Miller

To say that a lot has changed since the early 2000s is an understatement, especially when it comes to fashion. The trends that once ruled the world—low rise jeans, UGG boots, and Juicy Couture—have all cycled back into the spotlight. Though nostalgia has its limits, some popular aughts styles deserve a comeback. Case in point: when Sienna Miller stepped out in Manhattan yesterday afternoon, she did so in a look straight out of 2005. In her denim Levi’s cutoffs, Isabel Marant belt, and army surplus jacket, Miller channeled the look of the Glastonbury Music Festival, an event whose style she helped to define.

Back when large outdoor gatherings were commonplace, tastemakers like Miller, Kate Moss, and Alexa Chung stomped their way through Pilton, Somerset in short-shorts, Wellington boots, and sunglasses as they watched sets from Kaiser Chiefs and Arctic Monkeys. The casual, bohemian outfits worn by Miller and her ilk proved influential, and the event emerged as a place to be seen. If Coachella was the place to break out the flower crown and go ethereal, Glastonbury offered its celebrity attendees a chance to cultivate grungy glamour in their tank tops, oversized belts, and muddy boots.

Miller has always found ways to make even the simplest pieces feel elevated, but her cutoffs, white Rag and Bone Victorine shades, and baggy jacket were reminiscent of the style she favored a decade earlier. Updating the look with a few changes—t-strap sandals instead of ankle boots, a minimalist carryall from Frame rather than an oversized, woven hobo bag—she made a case for a festival fashion resurgence, right in time for reemergence.
