Denim/jeans were invented in the late 18th century by Jacob Davis and Levi Strauss to provide comfortable clothing for factory workers. They became popular casual wear for both men and women in the 1950s-1960s. Today, jeans have become a daily staple across ages and cultures worldwide. When buying jeans, make sure to consider comfort, flexibility, quality, fit and current styles to find the best pair. Properly fitting jeans that are comfortable and on-trend can improve one's presentation and confidence.
