Americans spent more than $14 billion on jeans in 2004 and $15 billion in 2005.
Evolution of the garment
Initially, jeans were simply sturdy trousers worn by workers, especially in the factories during World War II. During this period, men's jeans had the zipper down the front, whereas women's jeans had the zipper down the right side. By the 1960s, both men's and women's jeans had the zipper down the front. Historic photographs indicate that in the decades before they became a staple of fashion, jeans generally fit quite loosely, much like a pair of bib overalls without the bib. Indeed, until 1960, Levi Strauss denominated its flagship product "waist overalls" rather than "jeans".
