If there’s one stylish celebrity that the Who What Wear team always takes note of, it’s Sienna Miller. Of course, there are the red carpet looks that set our group chat alight, but we’re also constantly taking style notes from her everyday outfits. Moving between smart tailoring and soft boho silhouettes, blending high-end pieces with expensive-looking high street wares, her wardrobe is truly enviable, and just now the style muse has stepped out in a Mango coat that we’ve all simultaneously added to our baskets.

It’s far from the first time that Sienna Miller has stepped out in a Mango piece. Just like us, she recognises the brand’s ability to make an affordable piece look like a high-end buy. Arriving at the press junket for ‘War’ yesterday, she was spotted wearing the Mango Tailored Wool Coat, a classic autumn/winter piece with sharp shoulders, a long silhouette and sleek grey colourway.
