Authentic 1940s military utility shirt crafted from durable olive drab herringbone twill (HBT) cotton. This true vintage piece features the iconic 13-star metal buttons and dual large chest pockets characteristic of WWII-era army fatigue jackets. The fabric shows a beautiful natural fade and heavy distressing, including fraying at the collar and hem, which adds significant character and a rugged, lived-in aesthetic. Perfect for collectors of militaria or those seeking a genuine workwear look with historical significance.
