WWII Costume
Step back into the 1940s with an authentic military look.
The WWII soldier costume is a classic choice for history enthusiasts, reenactors, and vintage theme parties. Based on the standard-issue US Army combat uniforms of the 1940s, this look represents the iconic 'GI' style. The outfit consists of an olive drab jacket and trousers, utility belt, helmet, and combat boots.
