During the French Revolution, wearing dress associated with the royalist "Ancien Régime" made the wearer a target for the Jacobins. Working class men of the era, many of whom were revolutionaries, came to be known as sans-culottes because they could not afford silk breeches and wore less expensive pantaloons instead. The term was first used as an insult by French officer Jean-Bernard Gauthier de Murnan but was reclaimed by these men around the time of the Demonstration of 20 June 1792.
