A pajama set gives the most coverage and is the easiest to answer the door in; a shirt-and-trouser pair also lets you wear the top on its own. Nightgowns are the coolest option because nothing is layered at the waist, and the length runs from short slip to midi. Camisole sets sit between the two — a strappy top with shorts.
Robes and nightshirts are here as well, and there is a full men's range of pajamas, robes and sleep bottoms.
