A garment specially designed/adapted to be worn by a person with a disability while sleeping at night. It may be a one-piece garment (a nightgown) or a two-piece garment (pyjamas) typically constructed with features that facilitate easy donning, fastening, and removal (e.g., wide sleeves or trouser legs, Velcro and zip fasteners), and sometimes with specially-made openings/flaps for visits to the toilet.
