Onesie

[Britney]

Onesie comes from the word one and means a one-piece suit, usually in the form you use for lazy days at home. It is also used for one-piece snowsuits and one-piece motorcycle suits. The word is sometimes spelled [onesy].
The name may be derived from the registered trademark [Onesies], which is a range of clothes for infant children. The word onesie (in singular) does however, in modern usage, more often mean a suit in adult size.
