The top generally constitutes of a kurta or Kameez. The kurta is generally cotton shirt with a loose fit while a kameez is longer and is embroidered. The bottom could be a dhoti, pajama, churidar, or salwaar. The dhoti is a piece of uncut cloth which is tied while pyjama are trousers with loose fit. Churidaars are tight fitting slacks while salwaars are loose pants gathered at the ankles. Jodphur suits with long jackets are also popular in modern times. A turban could be worn by various ethnic groups.
