Sienna Miller was seen stepping out in London’s SoHo neighborhood this Friday with boyfriend Oli Green while sporting the perfect pair of boots for the transition from fall to winter. The star wore a classic and casual look, a loose knit top and shorts, but added some polish with a pair of Toova leather knee-high boots from Dune London.

Sienna Miller provides inspiration for those who strive to look put together even when just running to the grocery store or post office. Out on the SoHo streets, she opted for a mostly played-down look, wearing a navy top and tailored Bermuda shorts while carrying a woven handbag. The boots helped add a subtly refined touch to the look.

Dune London’s Toova leather knee-high boots are mostly flat with a slight block heel. They have a minimalist, sleek black design that goes with pretty much everything, a versatile bit of footwear that can make off-duty outfits look just a bit more refined. There’s an almost campus-like quality to Miller’s wardrobe choice, a cozy chic look that could make a person nostalgic for fall semesters back in college.

Bermuda shorts and boots have become something of a trend in recent months, the look experiencing a notable surge among Gen Z wearers this summer in New York City. Most paired their Bermuda shorts with slightly flashier boots than those seen on Miller, often opting for biker boots embellished with buckles.

Gen Z short-wearers also prefer something a bit less refined, often opting for a slightly rocker look with distressed shorts or shots sporting strategically placed patchwork. This makes it all the more impressive that Miller was able to make the trend work for her.

Miller paired down the edges of the Bermuda shorts and boots fad to incorporate a slightly more professional version of the outfit. This is no surprise given she has a history of making her everyday looks seem aspirational thanks to small-but-noteworthy choices in shoes. The star is a well-documented fan of Jude’s Mixer Sandals. Much like how she styled her Dune London boots with a more tempered outfit, Miller often uses Mixer Sandals to make casual attire like an oversized t-shirt and jeans or a sweater and loose trousers look classier.
