When did people start wearing underwear?

The history of underwear dates back to ancient civilizations, with evidence suggesting that garments resembling modern underwear were worn as early as 3000 BCE. In ancient Egypt, men and women used linen loincloths, while the Greeks and Romans also had similar garments. By the Middle Ages, tighter-fitting undergarments became common in Europe, eventually evolving into the diverse styles of underwear we see today.
