COS Autumn Winter 2026 presents a collective portrait of the faces defining the spirit of today, captured on the storied streets of New York. Distilling classic tailoring through a modern lens, this single-breasted blazer is crafted from a wool-twill suiting cloth sourced from the renowned Mario Bellucci mill in Italy's Prato textile district. Topstitched seams and split hem create definition, while the midnight hue underscores the polished restraint of the collection. Style it with the matching trousers or skirt for a contemporary take on suiting.
