Onesie (jumpsuit)
Onesie is a commonly used word for loose-fitting casual jumpsuits for adults, made of knit cotton (as used in sweatshirts), fleece, or chenille. They are mostly intended as loungewear or sleepwear, but have gained significant popularity as stylish street fashion. In the UK, the onesie became very popular during the late 2000s and early 2010s.
Adult onesie fashion craze
The company and product was initially conceptualized and marketed by entrepreneur and musician, Steve Pandi; originally intended as a gimmick his rock band would wear during shows. Being the first and only vendor of the popular onesie pajamas, the company quickly grew and began to appear on television as early as 2000 on Oxygen TV's "Pajama Party" television show.
Adult onesies quickly infiltrate pop-culture in the U.S.

In 2007 the company's adult onesie was a popular gift among celebrities when JumpinJammerz was included in the 2007 Academy Awards (Oscars) and Emmy Awards gifting events. By 2008 imitators began to replicate the onesie, again feeding into the craze. In 2009 a mix of JumpinJammerz onesies and their new competitor onesies appeared in a Saturday Night Live skit with James Franco.
