The first known underwear dates back almost 7000 years, when prehistoric man used leather to cover and protect his loins while running prehistoric errands. For several millennia, not much changed. Ancient Egyptian art shows everyone from the pharaohs on down the line decked out in loincloths of their own.
Why is it called underwear? The prevailing theory is that the name comes from the fact that early versions of this undergarment were actually two separate legs that had to be “drawn” up and tied in place, hence why we still refer to underwear as “pairs” even though they are single garments now – “a pair of drawers”, “a pair of underwear.”
The average American woman owns approximately 21 pairs of underwear. A 2008 survey revealed that 9% of men in America have underwear that is at least 10 years old.
