What is "nightwear"?

Nightwear is a type of clothing worn for sleeping or lounging at home. It is designed to provide comfort and ease of movement during the night. Typically made from lightweight and breathable materials such as cotton, silk, or satin, nightwear can come in a range of styles including pajamas, nightgowns, nightshirts, robes, and more. Depending on the climate and personal preference, nightwear can be long-sleeved or short-sleeved, full-length or short, loose or form-fitting. While its primary purpose is for sleeping, nightwear can also be worn for relaxing at home or during leisure time.
