An official photo describing the kit of a British infantryman in 1939. Note that the gas mask ('respirator') and anti-chemical warfare cape are parts of the outfit, remnants of WW1 memories. In actual combat, and marching with full kit, the British infantryman would carry a pack known as a "valise" that contained more clothing and personal items. Officers wore the exact same uniform save for markings of their rank.
Wes and Willy Little Boys' Slim Football Long Sleeve Pajama 33, UM Green, 5. Tight fitting to meet government standards for children's pajamas. Patented football pants with detailed stitching to mimick the real uniform. Subtle features make this pj look like a real football uniform.
