Jumpsuits are a one-piece garment that covers both the upper and lower body and is usually worn for casual or formal occasions. However, there are various other terms used for jumpsuits, depending on the style and material. One such synonym is onesies, which is typically used for children's clothing. Catsuits and unitards are also comparable to jumpsuits, with the former being typically used for performance and the latter for exercise or dance. Rompers are another alternative, typically shorter in length and slightly more casual in style. Additionally, playsuits and boiler suits are synonyms for jumpsuits that have gained popularity in recent years.
