The Kaupinam

The Kaupina It is a loin cloth passed between the legs and held by a string at the waist, just enough to cover the private parts. The remainder of the cloth acts as a curtain. Kaupina is a distinctly Indian form of clothing from ancient times. Even today (2006) one can come across priests, fishermen, craftsmen, laborers, tribals, and ascetics wearing only the kaupina. Even women (during their menstrual cycles) used to wear kaupina. People who wore other attires (like dhoti or sari ) also wore kaupina as an undergarment. But its use has decreased after the arrival of machine-made undergarments.
