Pajamas
Pajamas (US) or pyjamas (Commonwealth) (/pəˈdʒɑːməz, pɪ-, -ˈdʒæ-/ pə-JAH-məz, pih-, -JAM-əz), sometimes colloquially shortened to PJs,[1] jammies,[2] jim-jams, or in South Asia, night suits, are several related types of clothing worn as nightwear or while lounging. Pajamas are soft garments derived from the Indian and Iranian bottom-wear, the pyjamas, which were adopted in the Western world as nightwear.

In the United States, pajamas for children are required to comply with fire safety regulations. If made of flammable fabric, such as cotton, they must be tight fitting. Loose-fitting pajamas must be treated with a fire retardant.[7] Regulations in the United Kingdom are less stringent; pajamas which do not comply with fire safety standards may be sold, but must be labelled "KEEP AWAY FROM FIRE".[8]
