At last the weather has settled into a rhythm, and the cold days are now a constant. With our wardrobes set firmly to winter mode, most of us are in the midst of compiling chic winter outfits to see us through the coming months, and along the way may have found a few gaps where trending winter buys should be. Just in time, COS has launched its new collection and, in doing so, has ticked off five key winter trends.

From bold funnel-neck collars to eye-catching check patterns, COS's approach to the winter trends remains true to form, with longevity and quality composition at its core. These aren't fleeting trends, but rather striking designs that feel contemporary for winter 2026 and will continue to be integral wardrobe staples in a refined wardrobe for many years to come. For COS' masterclass in cold-weather dressing, the brand leans into the elegance of textures with brushed blazers and cashmere knits. Rich fabrics bring a serious dose of sophistication to our staples, from insulating merino wool to sleek satin.

As ever, COS reminds us that whilst it's a high-street brand, it's an expert in expensive-looking tailoring, with a selection of perfectly pleated pieces; any one of which would instantly upgrade your winter looks, or mix and match a few that will no doubt be longstanding favourites for years to come.
