In the final years of the California gold rush, a miner’s wife faced a simple but persistent problem: her husband kept tearing through his work pants. Their tailor, Jacob Davis, came up with a solution that would change fashion forever adding copper rivets to points of strain like pocket corners and the base of the button fly.
The reinforced “riveted pants” were an instant hit and, without Davis realizing it then, marked the birth of the blue jean, a garment that would eventually become synonymous with American identity.
“Jeans have democratized American fashion,” said Shawn Grain Carter, a professor at the Fashion Institute of Technology. “People around the world associate them with American Western culture and everyone wears denim, regardless of class or politics.”
Today, denim is a powerhouse commercial category. The global market reached $101 billion this year, up 28% since 2020, according to Euromonitor International. Major brands such as Levi Strauss and American Eagle are leaning on stars like Sydney Sweeney and Beyoncé to attract shoppers and stabilize sales in a shaky economy.
Levi Strauss and the Birth of Blue Jeans
Davis’ riveted trousers then known as “waist overalls” sold so quickly that he needed a partner to secure a patent. He reached out to Levi Strauss, a Bavarian immigrant and successful San Francisco wholesaler who supplied the denim Davis used.
“The secret of them Pents is the Rivits,” Davis famously wrote in a letter to Strauss, noting he couldn’t keep up with demand.
Strauss immediately recognized the business opportunity. On May 20, 1873, the pair patented the riveted-pants design and opened a factory on Fremont Street in San Francisco. With Strauss’ distribution network, their durable overalls spread nationwide, becoming essential gear for miners, cowboys, farmers, and other laborers.
From Workwear to Leisurewear
For decades, jeans were reserved for rugged work environments. But early 20th-century denim makers sought new customers. Manufacturers introduced variations like “spring bottom pants” slightly flared, more tailored styles aimed at foremen rather than laborers.
In 1934, Levi’s released the first jeans for women. Around the same time, denim entered the leisure market thanks to activities like dude ranch vacations, horseback riding, and camping. Travelers adopted the cowboy aesthetic as fashionable resort wear, and companies advertised their jeans as “dude ranch duds” and “authentic western riding wear.”
Still, denim didn’t become everyday casual wear until after World War II.
The Postwar Casual Revolution
After years of rationing and wartime austerity, Americans were eager to spend again. They bought cars, appliances—and new wardrobes.
“With more disposable income, there was a push for leisure clothes play clothes, fun clothes, outfits for backyard barbecues,” said fashion historian Sonya Abrego.
As denim manufacturers campaigned for jeans to be allowed in schools, they expanded their audience even further. By the 1960s, jeans came in a wide array of styles, colors, and fits. They emerged as symbols of the counterculture and became fixtures in Hollywood films.
The 1970s cemented denim as fashion: bell-bottoms flourished, and the first designer jeans—by brands like Calvin Klein and Gloria Vanderbilt—hit the market, decoupling denim from its workwear roots.
The Long Reign of Denim
From the 19th century to today, denim has persisted through every shift in style. Silhouettes and washes may evolve, but jeans never truly fall out of fashion.
