In the 1920s, jeans were considered popular Western wear worn by miners, cowboys and other workers who needed durable clothing that could withstand wear and tear.
In 1936, Levi Strauss added his signature red flag to the back pocket of jeans, making it the first item of clothing to have an outside label. It was also in the 1930s that Vogue featured its first model in denim on the cover, hinting that jeans could perhaps be a fashion statement, and not just reserved as practical clothing for working men.
