Evaluating rock art imagery and other related disoveries of a woven (textile) hunting disguise. Forager / hunter gatherer California, Great Basin or the American Southwest? However, anywhere in the world such garments were fashioned?
Although is not exactly textile (unless there was a lot of fibrous plant material in it), but you might consider another type of full-body disguise, this time olfactory.
Elephant hunters covering themselves in dung to mask their scent (olfactory "invisibility". An excellent recent article by Agam and Barkai 2018 "Elephant and Mammoth Hunting during the Paleolithic: A Review of the Relevant Archaeological, Ethnographic and Ethno-Historical Records," cite Carrington on p.12 of their work. You might look into that. Possibly on ReasearchGate. Ciao!
