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.
