    Yes, Sienna Miller has long been a style muse. Her boho looks are always a favourite, as was her sell-out collection with M&S—but last week's style combination proves even her easy everyday outfits are worth a moment of our attention. It seems Sienna has solved our dilemma of what to wear in this unusually warm autumn: white jeans, a classic navy knit and a statement red jacket.

    While there's nothing necessarily wow-making about this particular outfit, it's one that's actually wearable while touching on a number of current trends: primary colour clashing, the bandana necktie and the bold pop of red. The shade being a key one to note this season, with Prada, Schiaparelli, Alaïa, McQueen making it a focal point of their Autumn/Winter 26 runways. And in true Sienna style, it's genuinely practical, not overly polished just for the cameras.

    To see us through the cold mornings and warm afternoons, the actress has also opted for an underrated shoe: a simple black leather slip-on that really can work for any occasion, even the office. Just scroll below to see how we're creating this everyday outfit.
