The thong is believed to be one of the earliest forms of human clothing and is also thought to have been worn mostly or exclusively by men. The thong was first worn nearly 75,000 years ago. Many tribal peoples, such as some of the Khoisan people of southern Africa, wore thongs for many centuries. Much like the Japanese fundoshi, these early garments were made with the male genitalia in mind. According to fashion historians, the first public appearance of the thong in the United States was at the 1939 New York World’s Fair. This resulted from Fiorello LaGuardia, the Mayor of New York City, ordering the city’s nude dancers to cover themselves.
