The 1942 Dated Blue British Army PT (Physical Training) Shorts were a type of athletic shorts worn by soldiers in the British Army during World War II. These shorts were designed for soldiers to wear during their physical training exercises, including running, calisthenics, and other workouts. They were made of a lightweight and breathable blue-colored cotton fabric, which was comfortable to wear during exercise.

The shorts featured a waistband with a drawstring, which allowed soldiers to adjust the fit to their liking. They were typically worn with a matching blue t-shirt or tank top for a complete PT outfit. The shorts were designed to be functional and practical, allowing soldiers to move freely during their workouts.
