These women wearing the skirts and bowler hats are called ¨cholitas¨. The word comes from Aymara and means of mixed race (spanish and indigenous). It no longer carries the negative connotation that is used to. They are used mostly by indigenous women now.
That´s my bus from Puno (Peru) to La Paz (Bolivia)! We were crossing the Strait of Tiquina of Lake Titicaca. All the passengers got off and took a separate, and slightly more stable boat.
Arriving in La Paz, signs of support for Evo Morales - Bolivia´s first indigenous (Aymara) president.
