A depiction of Villa's early life would require a very simple costume -- a loose white shirt and slacks. He would have very few accessories -- perhaps not even shoes. Villa's early life was very poor. He worked in the fields and lacked the means to buy the lavish clothing he favored in later life.
The iconic image of Pancho Villa has him wearing a broad-brimmed sombrero, a uniform and two bandoliers crossed over his chest. In this phase of his life, Villa is almost always wearing boots and may be accurately depicted carrying a rifle.
When he ruled much of northern Mexico, Villa was photographed in the full regalia of a Mexican general. He wore the visor cap and high-collared general's uniform common during WWI -- although he added his own flair by combining them with thigh-high leather boots.
Pancho Villa was more a warlord than a politician, yet he moved in political circles on both sides of the border. In this incarnation, Villa often wore a tweedy three-piece suit with an ascot or bow tie. He was sometimes photographed wearing a pith helmet or a fedora with such an ensemble.
