National Blue Jeans Day

National Blue Jeans Day is on December 5 in the United States. This timeless classic remains a staple in almost everyone’s closet. Throughout its long history, blue jeans have undergone many transformations yet remain a beloved clothing item worldwide.

History

In 1873, Levi Strauss & Co. introduced denim overalls to the American West. Bavarian immigrant Levi Strauss had moved to New York to join his brothers’ dry goods business; two years later he partnered with tailor Jacob Davis, who added copper rivets to reinforce pockets and seams. Experimenting with different materials, they found denim ideal for durable workwear. While some accounts suggest the company originally sold blue-dyed canvas pants, others trace jeans’ origins to earlier European trousers dyed with imported Indian indigo.

By the 1930s, blue jeans were popular across the United States, appearing in countless Western films. Soldiers wore them during World War II, and by the 1950s, jeans had become a symbol of youth culture.

Interesting Facts

• Japanese designers have developed jeans infused with amino acids that claim to help slow aging.
