for the Navy really only has two colors = khaki and white. Depending upon your budget, Navy Nurses should have the white "summer" uniform (WWII so the uniform would have the knee length skirt
). Nurses were considered officers, btw, so they would be Ensigns to Lieutenants... The alternative is the khaki uniform. Epaulettes would have the medical corps insignia (gold oak leaf).
Casual dress might consist of white shorts, button white shirt, and/or white T-Shirt...
