We all know Sienna Miller can knock it out of the ballpark when it comes to dressing for fancy events (last week's wedding-guest ensemble at Ellie Goulding's big day was a welcome reminder), 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.
We've noticed over the past few weeks that Sienna has been photographed on the streets of New York City—where she's lived for quite some time—looking like the stylish but effortless woman we'd all like to be in our downtime. Her outfits have been perfect for weekend strolls, working-from-home days or brunching, and they all appear to revolve around a very clever, very concise capsule wardrobe. Highly interchangeable, it's exactly the kind of sensible, economical tack we'd like to more often take with our own closets. Buy less, buy better, get more wear out of everything: Miller is a maestro when it comes to this. Keep scrolling to see the five key pillars of the Brit girl's core laid-back wardrobe, and then shop them for yourself.
1. Roomy Shoulder Bag
Style Notes: This Proenza Schouler whipstitched tote bag has been a part of Sienna's repertoire for some time now. It's an expensive It bag for sure, but one that's made to the highest standards, and (if looked after properly) it really does balance out on the cost-per-wear scales.
Style Notes: We've noticed Sienna wearing these pleat-fronted sailor-style trousers quite a bit over the summer months. They're a great alternative to jeans when you want to feel a little smarter but still innocuous and easy enough to fling on with almost anything.
Style Notes: To top off many a cool look, Miller often turns to her time-honoured classic Ray-Ban Wayfarers. Sunglasses trends come and go, but if these suit your face shape (and they do tend to work for most people), they'll always look good.
