About This Answer

Levi's 501 jeans, introduced in 1890, represent the world's first blue jeans and revolutionized workwear and fashion. According to the Levi Strauss & Co. archives, the 501 model number was assigned in 1890 when the company began using lot numbers for different jean styles. The Smithsonian National Museum of American History displays original 501 jeans from the late 19th century. Fashion historians document how 501 jeans transitioned from work clothing to iconic fashion statements in the mid-20th century. The 501's copper rivets, five-pocket design, and durable denim construction created the template for virtually all modern jeans.
