Origin of shorts: They started in Europe and were known as Knee breeches. Originally developed for use by the military, shorter pants were a way to keep heavily packed and armed soldiers cool while serving in tropical climates. The style spread to the civilians who began to wear these so-called knee trousers as casual wear.
Four style variations:
i. Tennis Shorts were originally worn during tennis matches. These shorts are usually above the knee with pleated waist detail for maximum ease of movement
ii. Running shorts are short, yet somewhat loose fitting. Made of flexible, lightweight materials allow the wearer to run effortlessly.
iii. Bermuda shorts taper down to reach the knee caps. They generally have minimal extraneous detail.
iv. Cargo Shorts also known as Safari shorts are khaki shorts that have more than four pockets, often with flapped pockets on the sides of the leg. They are practical for camping and wilderness activities where tools such as a compass, pocket knife are required.
