Pajamas are a type of nightwear, mainly Western-style pants and a shirt that are separated into upper and lower parts.
It is made from materials that are soft to the touch and absorbent, such as silk, cotton, and linen.
There are a wide variety of types, including those that close the front of the upper body with buttons, those that are worn over the head, and (mainly for women) those that have a tunic on the upper body that resembles a nightgown.
There are various thicknesses of cloth and lengths of sleeves and pants, so you can wear them according to the season.
Loungewear is a type of clothing that is somewhere between pajamas and nightgowns, and there are some that you can wear without feeling out of place even if you sleep in them, put on a cardigan, or go out lightly.
