Although our prehistoric ancestors wore leather loincloths that have been excavated from more than 7,000 years ago, underwear as we know it didn’t become “normal” until the thirteenth century when it was tied at the waist and knees.
The ancient Greeks didn’t wear underwear, though their slaves sported a kind of loincloth.
The G in G-string stands for “groin” and was first used to describe the loincloths worn by North American Natives.
As women’s wear, G-strings first appeared in the 1930s when they were the exclusive attire of strippers.
