About Onesie

Since the 2000s, onesie has become a commonly used word for a particular style of 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 streetwear, especially in the UK and Australia; the onesie became very popular during the late 2000s and early 2010s as a street fashion.

Onesie was originally a term for an infant bodysuit, probably derived from Onesies®, which is a registered trademark for a certain range of infants’ clothes.


The term “onesies” (with an s at the end) is a brand name for infant bodysuits that is owned by the Gerber corporation, and the term is used generically for infant bodysuits in the US. There is little in common between the infant onesies and an adult onesie: the former is usually sleeveless and legless and snaps or buttons at the crotch. In 2008, when casual jumpsuits became increasingly popular, the press started discrediting them as “adult onesies,” and the name seems to have eroded to a generic word, dropping the final s in the process.


Man wears tiger onesie (Kigurumi) A type of onesie known as kigurumi (着ぐるみ), or “cosplay pajamas”, emerged as Japanese street fashion and spread outside Japan in 2009 when they were exported by the Kigu company. Kigurumi can also refer to a costumed character, and these types of clothing resemble various types of animals, similar to a mascot costume. They became popular worldwide following a viral video of Miley Cyrus twerking while wearing a unicorn kigurumi.
