Now that the brand has achieved worldwide fame, shoppers can walk in a Levi’s store and walk out covered head to toe in red-tabbed goods. For many, Levi’s is still known for one thing: denim pants. Founded in the mid-1800s, Levi’s is not only one of America’s oldest apparel brands, but one of the first mass-appeal denim brands. While there are now hundreds of brands making all kinds of denim, some of the best in the world still comes from Levi’s.
