Levi Strauss was the first man to begin producing special, strong trousers for working people. He made these trousers from a fabric called "denim"—a tough fabric probably came from a town named Nimes in France. Many people now think the English word "denim"conies from the (France) words "de Nimes", which means "from Nimes". Later, Strauss added special metal buttons to the trousers to make them even (strong) and they immediately became very popular.
