Made for workers under the 8 HOUR UNION label — the WWII DENIM CHORE COAT is a war-era civilian denim jacket 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.

The design of this civilian chore coat heavily references the joint U.S. Army-Navy issue Jumper, Dungaree Type II — a successor to the U.S. NAVY DENIM DUNGAREE JUMPER. Throughout World War II, Denim Jumpers were a popular choice for workwear, particularly for deck work on naval ships.
