Nightwear – also called sleepwear, nightclothes, or nightdress – is clothing designed to be worn while sleeping. The style of nightwear worn may vary with the seasons, with warmer styles being worn in colder conditions and vice versa. Some styles or materials are selected to be visually appealing or erotic in addition to their functional purposes.
Nightwear includes:
- Adult onesie - and other all-in-one footed sleepsuits worn by adults but similar to an infant onesie or children's blanket sleeper, usually made from cotton, and marketed under a number of different brand names.
- Babydoll - a short, sometimes sleeveless, loose-fitting nightgown or negligee for women, generally designed to resemble a young girl's nightgown.
- Blanket sleeper - a warm sleeping garment for infants and young children.
- Chemise - when used in reference to sleepwear, it is a delicate, usually provocative, loose-fitting, sleeveless, shirt-like lingerie, similar to babydoll, but tighter at the hips.
- Negligee - loose, sensuous nightwear for women usually made of sheer or semi-translucent fabrics and trimmed with lace or other fine material, and bows.
- Nightgown - loose hanging nightwear for women, typically made from cotton, silk, satin, or nylon.
- Nightshirt - loose-fitting garment, longer than a regular shirt.
- Nightcap - a warm cloth cap sometimes worn by women or men with pajamas or a nightgown.
- Pajamas - loose fitting two-piece garments for women, men and children. They may be made from cotton, silk, satin or synthetic materials; some couples may choose to have the woman wear the pajama top, while the man wears the bottom.
- Peignoir - a long outer garment for women usually sheer and made of chiffon. They are usually sold with a matching nightgown, negligee or panties.
Other types of garment are commonly worn for sleeping, but not exclusively so, including t-shirts, tank tops, sweatpants and gym shorts as well as underwear with no outer garment. Also, sleeping without clothing is not uncommon.

Children's Nightwear
On 22 December 2011, the U.S. Consumer Product Safety Commission (CPSC) issued a letter to manufacturers, distributors, importers and retailers reminding the apparel industry of the enforcement policy and their obligations associated with children’s sleepwear and loungewear.[3]
The Commission’s regulations define the term children’s sleepwear to include any product of wearing apparel (in sizes 0-14), such as nightgowns, pajamas, or similar or related items, such as robes, intended to be worn primarily for sleeping or activities related to sleeping, except: (1) diapers and underwear; (2) infant garments, sized for a child nine months of age or younger; and (3) tight-fitting garments that meet specific maximum dimensions.
All children’s sleepwear and loungewear sold in the US are required to comply with the Flammable Fabrics Act (FFA) using the standards for Flammability of Children’s Sleepwear 16 C.F.R. Parts 1615 and 1616. Moreover, they have to comply with the Consumer Product Safety Improvement Act of 2008 (CPSIA) requirements including tracking labels, a certificate of compliance, meeting requirements for lead content and surface coatings, and meeting requirements for phthalates.[4]
