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 some 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. Jacques Heim's and Louis Réard's original bikini from 1946 (that introduced the term bikini) had a culotte with a thong back. Fashion designer Rudi Gernreich, who in the mid-1960s created the first topless swimsuit, which he called the monokini, is credited with introducing the modern thong in 1974 when he designed a thong bikini in response to a ban on nude sunbathing by the Los Angeles City Council. Attitudes toward the wearing of g-strings vary geographically and across societies, as is usual with highly revealing clothing. Prior to its entrance into mainstream fashion, g-strings were primarily worn by exotic dancers. In the modern Western world, g-strings are more commonly marketed towards females but are worn by both sexes. During the 1980s, thongs were worn on stage by pop stars such as Cher and Madonna. By the 1980s, the style (for females) had made its way into most of the Western world; thong swimwear became even more popular through the 1980s due to TV shows such as Baywatch, in which numerous women were recorded wearing thong swimsuits. In the 1990s, the thong gained wider popularity in the United States as underwear and as swimwear, especially with women, but also men. In the US and Europe, the wearing of thongs by men was once mainly limited to the dance belt, the posing pouch for bodybuilders and the realm of male strippers. Men's thongs are now more widely available and commonly worn as day-to-day underwear or swimwear, with major retailers such as Kmart and popular fashion brands such as Calvin Klein selling men's thongs. Thongs are not marketed as strongly to men as they are to women; however, in Europe, thongs have been commonplace for many more years both as underwear and swimwear. In the 2000s, some people wore thongs with low-cut hipsters and deliberately exposed them over the top of their trousers, producing an effect popularly known as a whale tail.
