---- Trousers, or trousers, are an article of clothing worn on the lower part of the body, where the two legs are covered separately. They are part of both men's and women's clothing, usually with some differences in design. It owes its name to the Commedia dell'arte character, Pantalone, whose costume wears these typical long culottes. In turn, the mask was named after the Venetian spelling of the proper name Pantaleone, also belonging to a saint much venerated in the Lagoon. They open in the middle at the front or on the sides with a zip or buttons.
