It's time to admit defeat: the COS wide-leg trousers have us and our wardrobes totally and utterly hooked. It all comes down to three reasons – the fact that they're cut to perfection from durable fabrics, that they go with absolutely everything, and that they transcend seasons even better than our jeans.

Industry-famous and used by countless stylists and fashion influencers to elevate the most simple ensembles from “that'll do” to “wow”, they're one of those do-it-all items that – in a climate where we're all being a lot less frivolous with our spending – everyone could benefit from.

At around the £100 price mark, it's no wonder why COS' trews have us all standing to such attention. Since their launch, they've become the ultimate foundation piece that lets us build countless ‘fits. Right now, these are the trousers we turn to for every occasion, whether we’re teaming them with chunky jumpers, crisp shirts or going out tops. Slipping a puffer jacket over the top and teaming them with trainers gives a polished take on casual style, while adding a sharp blazer and heels looks like you mean business.

Sourcing trousers that hit every mark (i.e. are long enough in the leg, snug enough on the waist and loose enough on the hips) – without having to take them to a seamstress – is a rare occurrence these days. And if you do find said pair, you can certainly forget about them being under £100. TOM FORD, The Row and Saint Laurent are all known for their impeccable tailoring, but you'd be hard-pressed to find their trousers for less than £500 (unless they're on sale).

The COS wide-leg trousers in black, beige, grey and navy have become a non-negotiable for stylists and editors (who wear them to death with everything from shirts and blazers to t-shirts and loafers.) The brand's tailored trousers in wool are ideal for the colder weather – but COS also have linen-mix styles that will work in warmer weather, so you can bet they'll be added to our wardrobe rotation too.

A minimalist's dream come true, COS' wide-leg tailored trousers have many appealing qualities about them – hence their status – but our favourite detail, which is perhaps a lesser-known feature to passers by, is the elasticated waist. That's right, despite the fact that belt loops are present, you can rest assured that you don't have to wear one if you don't want to. The concealed adjustable button tab to the interior allows you to go from a well-fitted look to a low-slung one for that borrowed-from-the-boys finish. Forget straight-leg drawstring trousers and smart joggers; these are the way forward.

If you're not as taken by the cult wide-leg tailored wool style that the rest of the style set swear by, but you're searching for the ultimate pair of trousers, COS should still be your first port of call. The Swedish brand really knows how to create a cut that works on a myriad of body shapes, and the premium fabrics will last in your wardrobe.

Perhaps you fancy a straighter leg, in which case the Straight-leg wool-herringbone trousers will do the job – as will the tailored wool-flannel trousers in charcoal grey. If you prefer a tapered leg shape, COS have you covered too. Their barrel-leg wool trousers will also be a cold weather must-wear and work with trainers, heels and boots.
