I think, by this point, we're all aware of how great it is to have COS as a part of our great British high street. Whether you're a super-fan whose wardrobe only consists of the brand's minimalist designs or simply someone who pops in when you're in need of a perfect white T-shirt. Since it landed on our shores back in 2007, COS has managed to become the arbiter of understated style, expensive-looking basics and a haven for capsule wardrobe staples—all at the more affordable end of the spectrum. And that's the key to its success—COS has been democratising the "quiet luxury" aesthetic for many years before that phrase was on everyone's lips. It's where everyone from editors and A-list celebrities, to my mum turns if they want to find quality classics that are design-led and anything but boring.

Here atBest Knockoff Luxury Clothing , we have access to a whole heap of data that means we can really see what people are shopping (not just on our Instagram feeds). This way we get a genuine idea of the hero buys that are truly worth the money, and unsurprisingly COS is one of the brands that consistently crops up in these best seller lists. And so, since we all want to know the buys that have been backed by the hard evidence of other people's trust, I thought it would be insightful to share with you the brand's most popular buys of 2025 so far. From hero basics that you've probably been searching for, like perfect vests, T-shirts and shirts, to cult items like that studio bowling bag, and those wide-leg trousers—they're all in this list. As you'd expect, though, everything shares the signature COS characteristics, making them versatile, timeless investments you're unlikely to regret.
