Close your eyes. Think “jeans." Now open. They were 501s, right? They’re literally the blueprint for every pair of jeans in existence-burned into the world’s collective cortex ever since Levi Strauss (the man himself! ) invented them in 1873. To this day they’ve never gone out of style. And they never will. The original blue jean since 1873. A blank canvas for self-expression. Features the iconic straight fit and signature button fly.
