Is there any celebrity who epitomises London-girl style more than Sienna Miller? This weekend, while leaving the Apollo Theatre, where she's appearing in Cat on a Hot Tin Roof, the actress stepped out in what we'd describe as the most British of outfits. While you could be forgiven that this was a casual ensemble, there were a few style tweaks that ensured the look was seriously cool. There was the Burberry trench, a graphic tee from a cool new brand that's launching in September, skinny jeans that were slightly turned up and block heels that gave enough height to ensure her legs looked incredible. And you know what? You probably have all these items in your wardrobe already. If not, keep scrolling to see and shop the look.
