I’m a Stylist in My 40s — Here Are the 10 Best New-In Pieces at COS for Autumn

I love COS for those high-quality wardrobe essentials, with the odd ‘luxury’ piece here and there. And it’s a regular destination for me — from the perfect white tee to the kind of Winter coat you wear year after year. So when the Autumn range lands, I pay attention, and this year I’ve combed through every piece so you don’t have to. This Autumn sees COS at its finest: sharp tailoring, a palette of grey, ecru and chocolate, a jolt of the season’s biggest colour (red, if you hadn’t heard), and a little lace and satin to soften the edges.

So I’ve been through everything new-in and pulled the ten pieces I’d genuinely add to my own basket — the ones that feel the most current, the most flattering, and the easiest to fold into a wardrobe you already own. Here’s my edit, and why each one earns its place this Autumn.

1. Black Mock-Neck Trench Coat

Let’s start with outerwear, because it’s the buy that sets the tone for the whole season. The trench gets a rethink every few years, and the mock-neck version is this season’s smart update — that high, funnelled collar means you can skip the scarf (keep the wind out) and still look finished. COS is brilliant at this kind of tweak: classic enough to last, different enough to feel new. It’s the ideal weight for right now too, when the forecast can’t decide what it’s doing, and it works over tailoring as well as jeans and trainers. If your old trench is looking tired, this is the upgrade I’d advise.

2. Wide-Leg White Satin Trousers

From the most obvious buy to the boldest: winter white is the fastest shortcut to a modern outfit, and these wide-leg satin trousers are a bit of a showstopper. The satin catches the light, the wide leg is far more flattering with a drape like this — balance it with a knit up top — and the pale shade feels fresh sat against all the Autumnal browns. Satin bottoms paired with knits are having a real moment too, so a pair like this will take you from lunch to dinner without a second thought.

3. Lace Turtleneck Top

Lace is the season’s unexpected soft spot, ready and waiting to take the hard edge off all the tailoring. A lace turtleneck is the wearable way to do it, I’ve also added a neutral cami below that I would wear underneath too. The high neck keeps things sleek rather than fussy, and the sheer fabric adds texture under a blazer or a knit. I love it for the day-to-dark trick: tailored trousers and a coat while the sun’s up, then just the top under a blazer for dinner. A small dose of romance that rarely tips into twee.

4. Draped Midi Dress

Every edit needs a dress for the days you can’t be bothered to think, and this draped midi is a one-and-done kind of gem. The soft draping skims instead of clings, which is exactly why it works, and the midi length is spot-on for transitional style. And the joy of this one is the versatility, style with sandals and bare legs while it’s mild, then boots, tights, a knit pulled over the top and a coat to finish as it turns. File under: gets dressed for you.

5. Grey Tailored Wool Coat

Coat number two — because you can never have too much good outerwear that will truly last. If the trench is your everyday throw-on, this grey wool coat is the one you save for when it you need that added boost of polish. Grey is also doing the heavy lifting this Autumn — sharper than camel, warmer than black — and this one has the clean, minimalistic cut stylists are obsessed with as tailoring swings back into fashion. Layer it over knitwear and trousers on a weekday, or a slip dress and heels at the weekend, and it lifts the lot. Buy once, wear for a decade, a coat very well done.

6. Grey Cashmere Crew Neck

Every Autumn edit needs one faultless crew-neck, and grey cashmere is about as useful as knitwear gets. Tonal dressing — one shade, head to toe — is the low-effort trick everyone’s leaning on this season, so team this with grey trousers and you’ve a full outfit that looks like you tried far harder than you actually did. With something this pared-back it all comes down to the yarn: real cashmere drapes, softens and quite frankly, feels incredible to wear. If cashmere is out of budget Cos do knits very well all round so I’d look at their merino and lambswool alternatives too. Always responsibly sourced and the quality, in my experience, is always spot-on. A forever buy.

7. Longline Striped Cotton Shirt

The big shirt isn’t going anywhere, and a longline striped one is the most useful version going. Stripes are permanently in — no one’s ever regretted buying one — and the extra length and volume feel current while conveniently skimming the bits you’d rather skim. Do it buttoned and tucked into wide trousers, thrown open over a cami as a light layer, or wear long with straight jeans and loafers for that borrowed-from-the-boys look. You’ll be surprised how often you reach for this one.

8. Cashmere Mock-Neck Cardigan

Cardigans have had a serious glow-up, and this is a perfect example — done all the way up it reads as a top, left open it’s your softest layer. The mock neck is what makes it: a cleaner, sharper line than the usual grandpa cardi, and one of the big fashion trends we’re seeing for Autumn Winter 2026. I’d wear it buttoned under a wool coat for a double-knit, double-cosy moment, or open over the striped shirt above.

9. Pleated Tulip Trousers

These trousers, because I just totally fell for that tulip shape. Pleated at the waist and softly tapered to the ankle — is a proper stylist’s trick: roomy where you want it, neat where you don’t, and far more flattering than a straight leg. Pleated, fluid trousers are all over the season, part of the wider swing back to real tailoring. Wear them with a fine knit tucked in and loafers for the office, or a silky top and a heel come evening. Smart, comfortable, and a little bit clever — exactly my kind of trouser.

10. Merino V-Neck With a Pop of Red

And to finish, the piece I’m most excited about: red is THE colour of the season, and this fine merino V-neck is the least scary way to wear it. Forget top-to-toe — a single hit of red against all your greys and creams is what makes an outfit look sharp and intentional. It’s the thinnest pop of red and yet it really stands out and reads as a nod to the trends without feeling overwhelmed by them. The V is flattering and the knit is thin enough to layer, so slot it under either coat, or wear it over a white shirt with the collar out for a bit of a preppy look. Small buy, big pay-off — and a neat teaser for the red edit you can read below next.
