COS Is Already Winning Autumn—5 Rich-Looking Buys That Are Suddenly Going Viral
From sculptural cashmere and cult denim to sleek funnel-neck jackets and designer-looking bags, these are the COS buys set to dominate autumn
I spend a lot of my time looking for pieces that exude luxury, just without the accompanying designer price tag. And whilst plenty of brands have mastered the art of making affordable pieces look far more expensive than they are, there's one that, in my eyes, does it better than almost anyone else. Of course, I'm talking about COS.
Known for its clean lines, refined silhouettes and beautiful fabrics, COS has become my go-to destination for achieving that minimalist, The Row-adjacent aesthetic on the high street. And one scroll through the new-in section tells me autumn 2026 is going to be a particularly good season for the brand. It's already filled with the kind of pieces I predict will go viral—and subsequently become near-impossible to get hold of.

Some familiar favourites have returned. The Cashmere Crew-Neck Jumper, with its sculptural shape and chunky ribbed trims, has long been a fashion-person favourite, whilst the cult Chord straight-leg jeans are back in the deep indigo washes that feel particularly right for autumn. But alongside the COS classics, there are some seriously good newcomers. The Merino-Wool V-neck jumper, complete with clever layered detailing, is already proving popular amongst stylish women, and comes in everything from chic brown and red to a punchier purple colourway.
The outerwear offering is particularly strong, too. Funnel-neck jackets are making a major comeback for another autumn, and COS's ecru funnel-neck trench has already sold out, whilst its lightweight nylon iteration has returned in a line-up of suitably chic colours. Then there are the accessories. Sleek leather bowling bags, minimalist shoulder styles and the brand's now-signature crossbody bags are all back for the new season, ready to make even the simplest jeans-and-knit combination feel infinitely more polished.
If you're planning your autumn wardrobe now, these are the COS pieces I'd move quickly on. Keep scrolling to shop the new-season buys I predict will be everywhere before October.
