- Working Uniforms - Known as the Uniform of the Day (UOD), this is the core uniform that midshipmen wear. This uniform varies by season. During the warm weather months, midshipmen wear Service Khakis, comprised of a short-sleeve shirt, long pants, black shoes, and a garrison or "fore and aft" cap. Officers wear the traditional "high pressure cover", so-called because of its tight fit around the head. During cold weather months, the UOD changes to Winter Blue, which includes a heavier black long-sleeve shirt and pants, black shoes, and a black garrison cap or white high-pressure hat. Topcoats include the convoy coat in winter, or the A-Jacket in spring and fall.
Black replaced the grey tie decades ago. Sad to see the HY uniform go by the wayside, as much as they were a pain I always thought they looked sharp.
