Levi's is an iconic American brand known for its jeans that was originally founded in the late 1800s. While Levi's jeans were once ubiquitous, the brand struggled in recent decades as it diversified its product lines and launched many new styles. Experts argue that to regain its former strength, Levi's needs to narrow its focus, intensify its core brands like the 501 jeans, and avoid undermining its original brand through too much diversification and innovation. A limited re-release of vintage 501s was successful, but only time will tell if this signals a shift back to emphasizing Levi's strengths.
