"Jeans" is an abbreviation for "blue jeans," which were created in 1873 by Jacob Davis and Levi Strauss. Jeans as a word for pants originated in Genoa, Italy, where cotton corduroy, known as jean or jeane, was made. Genoa's Republic exported jeans all across Europe. When World War II ended, American manufacturers took over the market share from European companies. In America, most jeans are now made in Mexico and China. The United States is the world's largest producer of denim fabric. In 2014, Americans spent $750 million on jeans; the average cost of making one pair was $125. New York is the center of the men's apparel industry; it is also a major hub for the diamond industry. The International Chamber of Commerce estimates that 70,000 people are working in the jeans industry in the United States. That's about 5% of the total number of jobs available in the country. Manufacturing works such as sewing, stitching, cutting, and dying parts of the body with chemicals to create new products or modify existing ones are needed to make jeans. The average age of someone who works in the jeans industry is 36. They usually start out as interns and then move up to full-time employment. Most work in small factories that produce custom clothes for large brands. Some famous names in the industry include Lee, Wrangler, True Religion, Dockers, and Banana Republic.
