Sienna Miller just made a serious case for autumn pastels in a gorgeously boho outfit with astonishingly chic sunglasses
Forget browns and reds, Sienna just showed why pastels could be the autumn colour trend to watch


The queen of boho strikes again. Sienna Miller just attended the Chloé Womenswear Spring-Summer 2025 runway show in the perfect pastel look that has us ditching chocolate browns in favour of pinks and blues this season.
It's likely that your autumn capsule wardrobe is stuffed full of sleek neutrals - and rightly so. But who says pastels are just for spring? After seeing Sienna Miller at Paris Fashion Week in the perfect combination of baby blue and light wash pink, we're considering bringing the hues into our seasonal outfit formulas.
We fall in love with pretty much anything the actor wears, and her latest look is no exception. Reinventing a classic combination of high waisted trousers and a cropped jacket in a playful yet sophisticated way, we're suitably inspired to play around with our cold weather outfit palettes.

Naturally, Sienna's whole look is Chloé - but we've managed to find some similar items on the high street to help you channel her look on a budget. The perfect pieces to add some fun to your autumn and winter wardrobes that will see you all the way through to spring, these are truly timeless buys.
Shop Sienna's style
With a trench-esque silhouette, Sienna's cropped jacket is one of a kind. But you can get a similar look with a puffy blue blouse that can be layered as outerwear throughout the transitional months. For even more ruffles, go for this H&M ruffled blouse or stick with this Mango denim jacket if you want a refined coat in the same colour palette.
We love the 70s style of Sienna's trousers - especially the front pocket detailing. These cotton LK Bennett flares boast a very similar look with added breathability. A stylish alternative to barrel leg jeans that will add a subtle hint of colour to your autumn outfits, they will take you anywhere.
Often, the only antidote to grey days is a colourful outfit that can lift your spirits. Whilst a neon green or vibrant tropical print may feel out of place for the colder months, pastels have the beauty of versatility, adding a hint of colour without too much fuss.
Pink and blue makes for a timeless colour combination, especially in softer tones. Although they're hardly revolutionary tones, we're expecting to see some new fashion colour trends for 2024 emerging in reaction to Sienna's characteristically boho outfit.
Wondering what is boho style? Sienna Miller epitomises it, and proves just how chic and refined it can be. Made up of floaty silhouettes and soft colourways, it balances comfort and sophistication beautifully. And just because summer is over, that doesn't mean boho dressing has to go out the window too.
