      In addition to pinpointing the next must-have item, an essential aspect of my job as a shopping editor is to analyze data to uncover the items that our readers truly love. Last year, a specific pair of jeans stood out from the rest, and since the initial surge in sales, their popularity has remained warranted. In light of Black Friday, the much-admired COS Arch jeans are now available at a 20% discount in the COS Black Friday Sale.

      Upon noticing the growing interest in these jeans, I decided to investigate whether they lived up to expectations. In brief, they certainly did. COS has long been a go-to brand for fashion enthusiasts and our own editors seeking exceptional denim, along with a selection of remarkable cashmere and accessories. The design of these jeans is what elevates them into the best-seller category. Staying true to form, COS adds a modern twist to a classic with a subtle barrel-leg silhouette that feels refreshing while remaining compatible with our sophisticated wardrobes.

      (Image credit: @florriealexander) The Arch jeans perfectly balance between straight-leg styles and bold horseshoe cuts. The fit is impeccable, the sizing accurate, and the relaxed style of these jeans guarantees that they can be effortlessly dressed up or down. Alongside my beloved straight-leg jeans (which are also on sale this Black Friday) and fun wide-leg options, when I'm seeking something a bit different, it's the COS Arch jeans that I reach for. Having worked on Black Friday sales for many years, I'm aware of how quickly the COS Black Friday deals sell out. So, continue scrolling to shop the Arch jeans before they inevitably run out, and check out more excellent denim deals below!
