Sienna Miller's War wardrobe is a masterclass in modern dressing, from court-ready tailoring to cosy autumn outfits
Here's how to recreate Carla Duval's best looks
Is everyone else hooked on Sienna Miller's new drama, War? Dominic West plays her billionaire husband, and the pair quickly become embroiled in a bitter divorce that only gets more acrimonious with each episode.
Sienna's character, Carla Duval, is a glamorous Hollywood star, so of course, her wardrobe is just one dreamy designer outfit after another. From sharp, court-ready tailoring to elegant red carpet dresses and cosy autumn outfit ideas, the fashion well and truly has me hooked on this series.
It's a wardrobe that feels both sophisticated and wearable, even though it's full of high-end labels like Dolce & Gabbana, Stella McCartney and Chloe - it's actually very easy to recreate if you know where to look...
Pinstripe suit
Snapped in Paris with her lawyers in tow, Carla wears The Frankie Shop Gainsford Neck Tie Shirt with a Dolce & Gabbana pinstripe suit and a smart Loewe bag.
I love this relaxed approach to tailoring. Chocolate brown is a much softer alternative to black, plus of course you can mix and match both the blazer and trousers for endless new outfit options.
Available in UK sizes 8 to 24, this suit is from one of our favourite British clothing brands and can be yours for a little over £100. The key to Carla's chic look is layering, so add a wool coat over the top to complete the power-dressing feel.
This is very similar to the shirt and tie Sienna is wearing, but it costs a fraction of the price. I love the Wall Street vibe it exudes.
Red carpet dress
Carla's red carpet premiere doesn't exactly go to plan, but she looks impossibly chic for the occasion. Her simple black high-neck gown looks beautiful with slicked-back hair and statement earrings.
If you've got a black-tie event in the diary or a particularly glamorous Christmas party, this classic black dress is the same style Sienna wears in War. It's the kind of piece you'll treasure forever, so it's worth the investment.
Alternatively, this ME+EM option will give the real deal a run for its money. The draped neckline is super flattering, and it needs minimal accessories to be a real showstopper. It's also available in striking red, too.
Featuring ruched detailing that will make you feel very confident whilst wearing it, this Reiss dress moves beautifully when you walk. It's got a little extra shoulder coverage compared to the ME+EM option.
Tapestry jacket
The oh-so-boho Chloe Boxy collarless jacket in tapestry jacquard is a piece I can see Sienna wearing in real life. You can actually hire her clothes from the series via the War Edit on the HURR platform, or you can find high street lookalikes that will do the trick below.
This jacket was one of Rachel Stevens' recent autumnal picks from Zara, and it's a great way to make your favourite jeans feel fresh this season. I love the neat fit and puffy shoulders.
You can save an extra 20% on this jacket at the moment, which makes it a total bargain. Sienna paired hers with the matching mini skirt, but this would look so sophisticated with black wide-leg trousers.
Jacquard jackets are everywhere this season, and this Karen Millen option is one of the best I've seen. The collarless cut and boxy silhouette are spot on.
Knitted co-ord
I have to admit I immediately bought a similar dress when I saw this scene in War. Isn't the colour of Sienna's co-ord perfect for autumn? She's wearing a matching top and skirt by Sienna Miller, but the Nobody's Child dress I've found is a great lookalike.
Burgundy is always a great choice at this time of year, and this asymmetric skirt would work well with a crisp white shirt and knee-high boots.
This was the dress I bought after watching this episode. It's such a comfortable design, and it works with everything from white trainers to winter boots.
This rib-knit dress will certainly see you through the season in style. The collar really elevates it, and it's also available in navy.
Bomber jacket
And just in case you might have missed it, here's Sienna's faux fur-trimmed bomber jacket, which she wore with what looks like a Cartier Trinity necklace. The silhouette feels really fresh and modern, and I love the khaki colour.
Combining several autumn/winter 2026 trends in one go, this jacket features military-inspired buttons that will grab everyone's attention. The fit runs large so you can layer your best cashmere jumpers underneath.
There are only limited sizes left in this jacket, but it's so good I just had to show you it. Don't you think it looks so much more expensive than £56?
If bomber jackets aren't normally your thing, the collar on this option might just change your mind. It's padded, too, to keep you cosy.
Beyond the brilliant wardrobe, War is well worth adding to your no-doubt busy watchlist. If, like me, you're keen to see more of Carla Duval's enviable outfits, here's everything you need to know about how to watch War.
