Sienna Miller Just Wore the Perfect Casual Jeans Outfit, and I Already Own Every Single Item

I have long been an admirer of Sienna Miller's effortless style, and it seems that this won't be changing any time soon. After a whirlwind trip to Cannes Film Festival where the actor stole our attention in a boho-inspired Chloé gown, she's once again become a talking point in the Who What Wear UK office, this time for her elevated take on off-duty style.
Stepping out in London this week, Miller crafted a polished ensemble that's just become my template for easy weekday elegance. To contrast the formal feel of a grey blazer, she styled it with the sleeves casually scrunched up to her elbow, showing some skin and relaxing the smart piece. Leaning further towards the casual side, she selected a pair of billowing horseshoe jeans to add volume to her look, along with a slouchy suede bag from Jimmy Choo to accessorise.
Finessing her outfit with some polished additions, Miller layered on two gold chain necklaces and selected a smart pair of pointed-toe boots to add an angular element to the slouchy shape of her jeans and bag. Inspired by Miller's styling choices, I'm eager to emulate this look at home, and luckily for me, my wardrobe already contains all of the staple items that make up the chic, celebrity-approved outfit.
To re-create Miller's look, style a blazer over your favourite wide-leg jeans and reach for a well-loved slouchy bag to finish it off. If, however, you're in the market for some fresh wardrobe additions, read on to discover the actor's style below, and see our edit of the best wide-leg and horseshoe jeans to shop this season.
