If you're anything like me—the kind of person who refuses to feel cold, even in the heart of winter—then you'll understand the importance of layering. As I write this, the outdoor temperature has dropped to zero, and my commitment to dressing warmly has only intensified. My not-so-secret strategy for keeping warm while maintaining a polished look? Investing in winter essentials like COS’s impressive collection of merino wool tops, many of which are featured in the COS Black Friday sale. COS has quietly emerged as the go-to destination for fashion editors seeking high-quality layering pieces: the renowned Merino Wool Top, which fits effortlessly under blazers, cardigans, and dresses is a reliable wardrobe essential—so much so that COS now offers it in high-neck, crew-neck, and slim-fit variations. And that's just the tip of the iceberg. The brand’s luxuriously soft Cable-Knit Jumper appears far more expensive than it is, alongside a range of sleek wool cardigans and high-neck knits that elevate winter dressing from chaotic to sophisticated. Every item embodies the same COS essence—clean lines, premium materials, and silhouettes that transform the simplest outfit into something subtly refined.
Junior fashion editor Imani is showcasing one of the many pieces in COS's Black Friday sale, such as the Flecked Chunky Wool-Alpaca Cardigan (was £119, now £95.20) (Image credit: @imani_athina). What differentiates these pieces, however, isn’t just their elegance. COS utilizes RWS-certified wool, ensuring that every fiber complies with the Responsible Wool Standard, which includes strict regulations regarding animal welfare and land management. When investing in wool, I want assurance of responsible sourcing—and COS is one of the few high-street brands that can confidently affirm this. Whether you’re commuting to work layered under a tailored jacket, enjoying a chilly weekend stroll, or dressing up for an evening out, these wool staples serve as foundational pieces you'll rely on throughout the winter and for many winters to come. Below, I’ve compiled the most stylish wool items worth snapping up during the Black Friday sales before they're gone.
