Sienna Miller's Winter Capsule Wardrobe Revolves Around These 7 Easy to Replicate Pieces

1 week ago 2

If there is one celebrity that our editors all agree has the most enviable wardrobe among the A-list, the answer has to be Sienna Miller. Sure, she consistently turns out red carpet looks that are well-worth discussing, but it's her everyday outfit rotation that has us well and truly hooked, and it's easy to see why. Seamlessly blending the the elegant and the laid-back, Sienna switches between runway pieces and high-street bargains (who can forget that Mango coat from last winter ago), and while most celebs are content with following trends, Sienna stays one step ahead, reminding us exactly why we fell in love with polished basics, casual denim and boho blouses in the first place.

Should you be wondering what Sienna will be wearing next (and frankly, aren't we all), a good indication is to look to some of the winter outfits she has been known to wear the most. Whether she's photographed off duty in London, or attending an event in New York, you can guarantee that whatever she opts for will be both comfortable and chic—the ideal combination for a chilly winter. So, how exactly does one channel Sienna's recognisable aesthetic?

1. THE BOXY BLAZER

Style Notes: Celebs, they're just like us. Or, at least, they know the power of a good blazer just as much as we do. Take away the jacket and a black tank and jeans might have felt a little underwhelming, add an oversized blazer with the sleeves pushed up and voila, the perfect low key look for work, weekend and everything in-between.

2. STATEMENT KNITS

Style Notes: While we've all had our heads turned by simple cardigans, Sienna has been stocking up on chunky crew neck knits—most notably the statement jumper. The key to these novelty knits looking less "ugly Christmas jumper" and more Aspen appropriate? Stick to tonal shades that look sleek and expensive tucked into a pair of leather trousers.

Shop Knitwear:

Fair Isle Alpaca-Blend Sweater

3. WIDE LEG JEANS

Style Notes: As much as the internet would have us believe that skinny jeans are "back", the evidence suggests a different story. Not only does Sienna stick to a relaxed fit but, in fact, the wider the better. Don't worry though, you needn't drag around your hems in the winter rain, she often teams jeans with a heel (crisis averted), and a deep indigo wash not only looks expensive, but covers a multitude of sins too.

Shop Wide Leg Denim:

4. LUXE LEATHER

Style Notes: It's officially leather weather! And this high-impact, low-effort outfit is made all the better by topping things off with a glossy longline coat. A trench, wool coat, or even a blazer would have worked well with these high-waisted trousers and patent boots, but let's face it—nothing says luxury quite like leather, and with the right pieces in your arsenal you can dress up everything from tees to leggings simply by throwing on a little extra polish.

Shop Leather:

5. LEOPARD PRINT

Style Notes: Big cat energy is back for A/W '24 (that is, if it ever left), so expect to see much more in the way of leopard print coats, bags, trousers and shoes over the next few months as we ease away from quiet luxury into party season. A case in point? Sienna's inverted take on the age old classic "jeans and a nice top".

6. COSY SHEARLING

Style Notes: It's the easiest thing to throw on to beat the cold snap, and shearling remains a wardrobe staple for it's comfort factor alone, but it also helps that sized up and layered over neutrals it happens to look ten out of ten too. Sienna's winter whites look has not only inspired us to eschew our trench coats in favour of something a little more substantial, but also how to style white jeans for cold weather too.

Shop Shearling:

Short Pile Jacket

A bestseller in the making.

Style Notes: We've all got a reliable party dress in the back of our wardrobes, but the fashion set know just how arresting a well tailored suit can be for formal occasions. Relying on one of her favourite silhouettes yet again (hello, blazer + wide-leg trousers), Sienna makes a convincing case for Studio 54 inspired partywear, and just get a load of that bag... Statement accessorising at it's finest.
