According to Lynn Downey, denim was created in the late 18th century. In the late 1800s, it began to become more of a part of general clothing. Denim jackets were originally created for the workplace; they were a part of the overall denim outfit that was rugged and durable, helping to keep parts of the body safe.
Denim Jackets became a serious part of fashion thanks to companies like Levi Strauss. The company began seeing success with denim jackets in the early 1900’s. Since then, major fashion companies such as Gucci and Givenchy have embraced and used the denim jacket, according to The Guardian.
