Jeans are trousers made from denim. Mainly designed for work, they became popular among teenagers starting in the 1950s. Historic brands include Levi's and Wrangler. Today, jeans are a very popular form of casual dress around the world and come in many styles and colors, with the "blue jeans" particularly identified with the American culture, especially the American Old West. Americans spent more than $14 billion on jeans in 2004. In 1895 you could buy jeans for $1.50. Today, some jeans cost $200 to $500 with limited-edition and collectibles costing up to $2000.
The earliest known precursor to jeans is the Indian export of a thick cotton cloth, in the 16th century, known as dungaree. Dyed in indigo, it was sold near the Dongarii Fort near Bombay, and cut by sailors to suit their needs.
