The USMC adopted the P-41 uniform in November 1941, which consisted of a jacket and pants. It was initially intended to be worn for work and training.

It has four copper-plated metal buttons on its front placket that has the initials of the USMC. Its cuff has two metal buttons and a buttonhole that can be used to adjust the size of the cuff.
