These 5 Pieces Make Up Sienna's Casual Capsule Wardrobe

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.

Every time Sienna steps out, we get another glimpse of 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.

2. Loose-Fit Trousers

Style Notes: We've noticed Sienna wearing these pleat-fronted sailor-style trousers quite a bit over the summer months, and will probably be seeing them throughout the rest of the year. 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.

3. Cute Tops

Style Notes: What does SM pair with her favourite navy trousers? A selection of sweet shirts and cute cropped knits, the latter being particularly useful for segueing into autumn.

4. Plimsolls

Style Notes: From classic Adidas Stan Smiths to totally unbranded and super-plain plimsolls, Sienna's never far away from a simple pair of sneaks.

5. Classic Sunglasses

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.
