I've Tried On So Many COS Trousers—From Wide-Leg to Barrel, These Are the Very Best
COS is known for its excellent trousers, and after trying on so many pairs, I've rounded up the very best styles in one concise edit.


Ask any one of our editors, or really any fashion person, who does the best trousers on the high street and they're likely to agree that it's COS. The brand is known for excelling in staple styles, with an attention to detail that makes every piece, despite the affordable price tag, look and feel like a designer buy. There's a consideration to the design process that sets its pieces apart, but is particularly prevalent in the precise cuts and perfectly placed pleats of its trousers. As an editor who has tried on a whole range of COS trousers, I thought I'd take the time to share the very best with you.
When it comes to my personal style, I'm known for almost always sticking to trousers or jeans. Dresses and skirts may appear from time to time in the warmest months, but the versatility and elegance of a great pair of trousers always draw me back in. Over the years, I've put a whole host of trousers to the test, from designer buys to affordable finds, and COS is one brand I frequent more than most when sharing my favourite pairs. All that to say. I'm quite discerning when it comes to tailored trousers, but I'm yet to find a COS pair that I don't adore.
By now, the brand is also well aware of its design prowess in this category. It's had best-selling styles for years, like the Relaxed Twill Wide-Leg Trousers that are consistently in motion between sold out and restocked. With each new season, the brand leans into trending styles, like this summer's return to Capris, as well as staple pieces like the standout selection of linen trousers that my fellow editor, Emily Dawes, put to the test just a few weeks ago.
Whether it's classics that you're drawn to or bolder trending styles, the high street brand has a way of making each design a long-term addition to your wardrobe. For those searching for relaxed wide-leg styles, there's a selection of perfectly draped pieces to choose from, whilst those looking for more adventurous barrel-leg styles will be satiated by the cotton, linen and denim offerings. In terms of fit, I've always found COS styles to fit true to size, though some may come up a little long on me (I'm 5'2"). Thankfully, most dry cleaners are able to easily take a few inches off a hem.
