We all know Sienna Miller can knock it out of the ballpark when it comes to dressing for fancy events (the blue dress she wore for The Sandman premier is still on my mind), but we’ve always appreciated the actress for her off-duty looks too. As the OG boho troubadour, it’s highly likely Sienna’s fashion choices have influenced every single one of us over the years, whether we’ve realised it or not. I know that my tiered hippie skirt and studded waist-belt collection probably wouldn’t have come to fruition if it weren’t for her mid-noughties aesthetic taking off so strongly. I’d even still quite like to own a pair of Vivienne Westwood pirate boots, but Miller’s wardrobe has grown up, and so have I, and it’s now her more casual, pared-back, minimalistic approach to everyday dressing that resonates with me.
