What is a Onesie?

A onesie, also called onsie, onesie pajamas, onesie pjs, onesie costume or Kigurumi is a garment for baby, children and adult that wraps them entirely in one piece: the feet are sometimes enclosed and the hands are free; the head is uncovered, but a hood may be present. Most onesies are produced with materials such as cotton, polyester or acrylic and are sometimes doubled inside with polar fleece.

The purpose of the onesie is to act as a warming garment to prevent you or your children from having cold. However, onesies can also be worn during the day as outerwear, home clothes or as a party costume.
