Behind nearly every item in the modern male wardrobe is a 'first of its kind' - the definitive item, often designed by a single company or brand for specialist use, on which all subsequent versions have been based. ICONS OF MENSWEAR examines, garment by garment, the most important and famous of these products - their provenance and history, the stories of their design, the brand/company that started it all and how the item shaped the way men dress today.
