What kind of unusual Halloween costume is this? (in my country, almost no one celebrates it)

Budget/easy undress mummy. Probably made from a single roll of gauze. I guess next they need to make an even more "budget" ghost costume out of a pillow case instead of a sheet. Just cut into three to get a skirt, chest cover, and head cover.
