One-piece pants are divided into trousers and shorts according to their length.
The jumpsuit originated from the pilot's parachuting suit, which is characterized by the combination of upper and lower clothes, generally long-sleeved trousers, and the overall appearance is more like work clothes. This design was later applied to the fashion design concept of women's wear, and the jacket also changed with long sleeves, short sleeves and sleeveless sleeves.
One-piece shorts originated from a girl's clothing style in Victorian era. Short sleeves, loose tailoring, and tight shorts legs ensure the breathability and comfort of clothes and facilitate activities. This application in women's fashion mainly reflects the sense of youth in age reduction.
