If the history of American clothing is written in denim, the Levi’s 501 is the blue-stained ink.
And yet its path from genuine workwear to everyday wardrobe stable didn’t happen overnight. Nor has the 501 always followed the same basic template we recognize today.

The iconic numbers date back to the 1890s, when Levi Strauss and Jacob Davis attached them to a pair of pants adorned with four pockets: three on the front (including a small one for coins) and another on the back.
But it would take until the turn of the century for the 501 to adopt its signature attribute: a second back pocket, which has since come standard on nearly every pair of jeans from Levi’s and otherwise.
