From the Order:
The short-sleeve khaki shirt with appropriate service trousers or skirt/slacks is designated as the service "C" uniform. During the winter season, commanders may, at their discretion when the weather requires, authorize the service "C" uniform. This uniform may be worn as a uniform of the day and for leave or liberty, unless otherwise prescribed by the commander, and may be prescribed for formations at parades or ceremonies on and off the military activity. This uniform will not be worn for formal or semiformal social events.
Officer and enlisted female service uniforms are the same, except officers wear their rank insignia on the shirt collar and enlisted Marines wear cloth insignia on their sleeves.
