The blue jean that started it all is the Levi's' button-fly 501 Original Jean. Made from 12.5 oz. 100% cotton, this jean is a bestseller because of its one-of-a-kind fit; a classic fit through the seat and thigh with straight leg and 17 1/4-inch leg openings. The 501 fits below the waist with a tilted waistband that pitches toward the front. The finishes have been hand treated and washed down to give them a soft and comfortable feel that you can wear true to size or a size up for a looser look. The Levi's 501 has a front button closure and five pocket styling for all your storage needs.
