The blue jean that started it all. The Levi's 501 Original Shrink-To-Fit Jean includes a button fly and still features Levi's famous regular fit through the seat and thigh but this style takes fit one step further -- it shrinks to a custom fit after the first wash, which means you can wash it, wear it, and break it in on your own!
