Young Brunette Girl Strips Her Pink Nightwear On The Bed

• 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.
