Levi's 505 jeans have been praised for their style, fit, and quality for almost 50 years. However, some customers have experienced issues with the fit and quality of the jeans, such as holes appearing on upper back pockets after multiple wears and washes. Additionally, some customers have found the stretch to be too thin and the color to be too dark. Despite these issues, many customers have found the jeans to be a great fit and have purchased multiple pairs.
