Jumpsuit
A jumpsuit is a one-piece garment with sleeves and legs and typically without integral coverings for feet, hands or head. The original jump suit is the functional one-piece garment used by parachuters. The original skydivers' jumpsuits were simple garments designed to insulate the body from the colder temperature that's associated with higher altitudes and minimize the risk of covering important handles and grips. Today, however, the garment has found other uses. Jumpsuits are generally regarded as a garment of convenience, especially for entertainers, as they are simpler, lighter and more flexible to wear. They have become  more of a put on and remove garment than an ensemble outfit. However, unless the jumpsuit has an opening on the rear (a "drop seat"), it is necessary to remove it entirely for bathroom use. Pilots and drivers. Aviators and astronauts sometimes wear insulated, fire-retardant jumpsuits or flight suits where other types of clothing can potentially float or flap about in zero gravity or during high-G maneuvers. Drivers in motor racing wear jumpsuits for protection against fire (called a fire suit) and (in the case of motorcycle racers) leather suits for abrasion. Prisoners. Jumpsuits are common as a  prison uniform, particularly in the United States. The clothing is a convenient way to determine who is an inmate and who is a corrections officer. Although bright orange uniforms are still in use, some institutions changed for other colors as orange jumpsuits became fashionable due to the influence of the Netflix series "Orange is the New Black." Furthermore, color-coded uniforms are fairly commonly used where different colors signify the inmate's custody level or issues like gender, potential safety risks, disciplinary history, severity of current charges and past convictions. Some institutions even went back to striped uniforms to prevent  escaped inmates from being mistaken for sanitation, utility or highway workers.
