COS Autumn Winter 2026 presents a collective portrait of the faces defining the spirit of today, captured on the storied streets of New York. A modern menswear archetype, this refined shirt is realized in richly tactile wool-flannel, imbuing its mélange tone with depth and nuance. The button-down collar, stepped hem and mother-of-pearl fastenings take cues from sartorialism. Style it with the matching trousers.
