The trench is a classic double-breasted belted coat with epaulettes, a storm flap (yoke) and a notched collar, whose silhouette has become one of the most recognisable in fashion. It was born as military dress: British officers wore trench coats in the trenches of the First World War (hence the name), and the firms Burberry and Aquascutum made it a legend. From the battlefield the trench passed into the civilian wardrobe, keeping its severe functional details. Its silhouette is restrained, elegant and timeless, equally fitting in the rain and as a style accent. The trench long ago transcended season to become a symbol of time-defying classics.
