It's safe to say Sienna Miller knows her stuff when it comes to style. From beautiful boho dresses to the best barrel leg jeans, if I could swap wardrobes with only one celebrity, Sienna's would be top of my wishlist.

So you can imagine how excited I was to see that not only has Sienna taken all the hard work out of winter coat shopping, but the style she's found is from one of our favourite British clothing brands. Bonus: at under £300, it's pretty affordable for a piece you're going to wear on repeat until spring.

Navy is a much softer alternative to black, but it's just as classic and will work with everything in your wardrobe, so it's well worth the investment.

It can be easily styled with all of the autumn/winter fashion colour trends 2025, from mocha mousse to tomato red, and don't make the mistake of following the fashion myth that black and navy don't go - they totally do!
