While barrel-leg jeans have dominated the denim trends for 2026 so far, Sienna Miller just made a case for a more refined and polished silhouette that’s worth wearing well into autumn.
Attending the West End Opening Gala of Abigail’s Party in London last week, she wore a pair of cropped bootcut jeans by Chloé. The cropped length and kicky hem felt polished yet still effortless enough for everyday wear.
She styled the jeans with the Phoebe Philo club slippers in shiny patent black leather, which made for the perfect pairing against her refined denim. Her Chloé small bracelet tote bag tied in the black leather to the rest of her look, while she accessorised further with the Elma Sunglasses from Jimmy Fairly, as well as some Sophie Buhai earrings and the Jessica McCormack Forget Me Knot bangle.
Get Sienna Miller's Look
These ME+EM jeans are a perfect alternative to Sienna's Chloé pair, with the denim staple boasting the same flared hem, cropped length and front patch pockets, too. Fitted at the hips before kicking out into a gentle bootcut, the proportions are perfectly balanced for a flattering fit.
These cropped jeans are available in both regular and petite sizes, so you can find the most flattering length for your frame.
Rather appropriately named the 'Sienna', these Mango jeans feature a subtle flared shape, and the cropped length is spot on for showing off your favourite flats.
The retro shape of these sunnies fits Sienna's overall look perfectly, plus the tortoiseshell frames are a much softer alternative to black. Don't make the mistake of thinking the best sunglasses are only for the summer months - you'll wear these all year round!
Sienna is a massive fan of Chloé's boho-meets-edgy style. For a saving of over £1k, this bag emulates the look with its rounded shape, metal details and top handle.
These loafers have a sleek, tailored shape that works beautifully with flared denim. Like Sienna's designer shoes, they have a squared-off toe and a minimal design for an understated finish.
While the best barrel leg jeans are always going to be an autumn capsule wardrobe favourite, introducing a new denim silhouette is the easy way to refresh your style for the new season.
Jeans and trainers are a pairing we’ll always turn to for autumn outfit ideas, but Sienna’s sleek, loafer-ballet-shoe hybrid feels like a more refined alternative this autumn. It's ideal for wearing with flared denim, especially in a cropped style, as it creates a balanced look against the wider hem.
With her chic shirt, Sienna’s look feels refined enough for the office and smart casual outfits in a way that outfits styled around barrel leg jeans sometimes don’t. The flared and structured silhouette of her jeans almost emulates the look of tailored trousers, meaning they can also elevate casual tops like T-shirts for a more comfortable and laidback style that still feels perfectly put-together.
Plus, this outfit formula works brilliantly for autumn and its transitional weather, since the shape of her jeans lends itself well to being layered up with a blazer or trench coat when the weather really cools down.
