Made for workers under the 8 HOUR UNION label — these WWII DENIM WORK TROUSERS are a war-era civilian blue jean made from 10 oz. grey weft denim.

During World War II, jeans and denim garments were classified as "staple work clothing" by the War Production Board. To support the war effort, the Office of Price Administration regulated the costs and construction details of these garments, ensuring they were affordable and conserved materials.

As a result, several mandated changes were implemented. Pocket flaps were removed from jackets, and rivets were taken off the crotch and watch pockets of jeans. A notable example is the prohibition of three-needle stitching, forcing manufacturers who specialized in this technique before the war to switch to two-needle stitching.

Further modifications were made based on material availability. For example, branded buttons were replaced with standard-issue buttons featuring a laurel leaf design and rivets were replaced with bar tacking.
