Jeans are a pair of pants which are made from the fabric denim. The word jeans comes from the French phrase bleu de G├¬nes, which is the blue of Genoa while denim originated in the French town of N├«mes, from which denim (de N├«mes) gets its name. Denim is made up of a mixture of different fabrics. It is essentially all cotton, but to get certain stretch in jeans, elastane or lycra will be added to the blend. The cotton can also be mixed with fibers like polyester, nylon, elasterell and spandex to produce different types of denim for different types of jeans.
