Denim trousers for sailors
Denim trousers were made in Chieri, a town near Turin, during the Renaissance and were popularized in the 19th century. These trousers were sold through the harbor of Genoa, which was the capital of the independent Republic of Genoa which was long an important naval and trading power. The Genoese Navy required all-purpose trousers for its sailors that could be worn while swabbing the deck and the denim material met this need. These trousers were laundered by dragging them in nets behind the ship, and the sea water and sun would gradually bleach them to white.
Jeans (at the time known as "dungarees"), along with light-blue stenciled "cambric" shirts, became part of the official working uniform of the United States Navy in the first part of the 20th Century. A working uniform was selected to protect traditional uniforms from becoming soiled or torn in the ship's rugged working environment, leaving them for ceremonial occasions. They were first issued in 1901, and were originally straight-legged but by the mid-20th century the trousers became Boot-cut style to permit ventilation in the ship's hotter working environments and to ensure sailors could shed their dungarees if they fell overboard or had to abandon ship.
