From classic pairs of blues to shirts, jackets and dresses, denim is a cornerstone of my capsule wardrobe. Throughout the year, jeans are my most reliable companion thanks to their ease of styling no matter the occasion. Heading to work? Add a blazer and loafers. Popping out for a coffee? It's a cosy knit and trainers for me. So, with jeans such a crucial pillar of my wardrobe, I take note when our readers show a particular interest in one specific pair, and lately, it's COS' Arch Jeans (£85) that we've seen creeping up the ranks through our data and across our social feeds. I decided to give them a go, and all I can say to the readers who guided me here is thank you.
After many years as a straight-leg devotee, denim styles have diversified in recent seasons, allowing for much more variety. New and interesting cuts have come to the fore, from loose wide-leg styles to colourful pairs—the latter of which I also recently tested out myself. And just as we're always in the know about the latest jeans trends and the newest style releases, we also have insights into our readers' current favourite pairs, which led me straight to COS' Arch style.
The Arch style bridges the gap between bolder barrel-leg cuts, which can come in exaggerated horseshoe silhouettes and the most classic straight pairs. As a brand that excels in tailoring and staples, it makes sense that COS would offer such a spot-on cut in its denim collection.
Many of us can attest to the trials and tribulations that come with denim shopping, but I've found that COS' denim fits true to size. The relaxed nature of this pair in particular, along with the tapered hem, adds a streamlined effect that not only offers a great shape but adds comfort too.
