[8] The G-string first appeared in costumes worn by showgirls in the United States in Earl Carroll's productions during the 1920s,[9] a period known as the Jazz Age or the Roaring Twenties.
[10] Before the Great Depression most performers made their own G-strings or bought them from traveling salesmen, but from the 1930s they were usually purchased from commercial manufacturers of burlesque costumes.
The Chicago area was the home of some of the largest manufacturers of G-strings and it also became the center of the burlesque shows in the United States.
In New York City, G-strings were worn by female dancers at risqué Broadway theatre shows during the Jazz Age.
"Strong" shows usually took place only when the police were not present, and they became rarer after 1936 when Fiorello H. La Guardia, the Mayor of New York City, organized a series of police raids on burlesque shows[13] and closed strip clubs in the city for the first time in its history.
