I've Done the Research: This Is *Exactly* What London's Chicest It Girls Are Buying This Autumn

For any fashionable dresser, September often feels like a special month. As summer slowly fades into autumn, for many, it means one thing: fashion month. Be it the maximalist prints, colours and embellished garments that decorate the streets of New York or the softly sophisticated, heritage-filled halls of Paris, each week brings something new. And my favourite just so happens to be London.

I know I'm biased (it’s the place I’ve called home for the better part of 10 years), or maybe the fashion just really is that good; either way, I’ve always considered London the most stylish capital of the Big Four. Whether you’re vintage-obsessed, subscribe to a Substack-styled aesthetic or favour a high-street hero, there's space for you in this city. You see, dressing in London is less about what you wear per se, and more about the polished-without-trying energy that defines your looks.

From Alexa Chung's rock-and-roll realness through to Lila Moss' nostalgia-inspired minimalism, though the aesthetic may change, true Londoners tend to have three or four pieces in common. From the perfect pair of tailored trousers to the shoes they wouldn't dream of parting with, I sifted through the social media feeds of my favourite It girls to uncover the pieces cropping up again and again this autumn.

The 5 Staples in Every Well-Dressed Londoner's Wardrobe This Autumn

1. The Timeless Trench

Style Notes: Trench coats are to Londoners what ballet flats are to Parisians: less of a piece of clothing and more of a cultural symbol. Functional enough for transitional weather, the longline coat is favoured by the Bond Street glitterati for its inherent polish, but also adapts (like London itself) to whoever wears it. For an autumn 2026 update, look for one in a vivid hue, like Marilyn's denim blue (pictured above). Finished with a black pointed-toe boot and a fitted pair of trousers, it's an easy way to inject a London-centric spin.

2. The Perfect Trousers

Style Notes: Trousers have been a capsule-wardrobe staple for decades, but in autumn 2026, swap ultra-baggy pairs for something a little sleeker. The '90s-inspired slimline style has quietly become an It-girl must-have. Clean without feeling corporate, polished without being overly prim, the relaxed silhouette elegantly skims the leg, elongating whilst giving you plenty of wiggle room. Whether styled with a billowing blouse, oversized shirt or graphic T-shirt, they’re an easy way to nod to nostalgia this season.

3. Functional Flats

Style Notes: Whilst trainers will always have a home in London, this year, ballet flats have well and truly made their mark on the city. Perfect for hopping on and off the Tube and practical enough for days when you’re clocking 20,000 steps, the style has quietly become something of an essential. Wear with fitted trousers or a slouchy pair of jeans for an effortless throw-on-and-go energy that feels perfect for the season ahead.

4. Pack-a-Punch Prints

Style Notes: Whether you use it as an accessory or go all-out in a statement coat, one thing's clear this season: the only rule for animal print is to wear it. Expect spotty faux-fur coats and the kind of bold zebra stripes reminiscent of '00s Roberto Cavalli. This year, prints have shed any sense of subtlety, so maximise a printed dress with a tiger-print boot or dive into an attention-grabbing coat.

5. Striking Structure

Style Notes: We've been loyal to tailoring for quite some time now (who doesn't own at least one big blazer to throw on with jeans?), but the coolest Londoners are pressing pause on everyday suiting in favour of something more sculptural. Adding drama and shape to basic ensembles, these pieces (such as sharply cut blazers or statement tops) instantly draw attention and hold the gaze. Wear with a simple pair of trousers, and the outfit feels instantly more considered, or follow Evie Mills' lead (pictured above) and wear it in dress form. Martini optional.
