The string thong has its roots in Brazil, where it emerged as a popular swimwear style in the 1980s. The design was initially met with controversy, but it eventually gained acceptance and spread to other parts of the world. Today, string thongs are worn by people of all ages and backgrounds, from beachgoers to professional athletes.
