What is one requirement for the fit of service uniforms?

The requirement for the fit of service uniforms emphasizes a comfortable fit while standing at attention, which ensures that personnel can maintain a proper posture and appearance without restriction. This allows Marines to look sharp and professional while still being able to perform necessary duties. The design of the uniform should accommodate movement and activity, yet it must also allow for the soldier to stand at attention comfortably, which is a key posture in military ceremonies and formations.

While adjustments for comfort and mobility are essential as well, the specific context here focuses on how the uniform should fit when an individual is standing in a formal position. This distinction is crucial in understanding military uniform standards, which prioritize both functionality and adherence to ceremonial protocols.
