The Levi’s 501 dates all the way back to the 1800s, with the 1901 variation originally being referred to as overalls. Made with a cinch back and buttons along the waist that allowed you to attach suspenders, the style welcomed the addition of a second back pocket, adhering to consumer demand and men’s fashion at that time. The pair features classic five-pocket styling, with other traditional design elements including a button fly and the Levi’s logo patch incorporated onto the back of the waist.
