Icelandic necropants

necropants
"If you want to make your own necropants (literally; nábrók) you have to get permission from a living man to use his skin after his death. After he has been buried you must dig up his body and flay the skin of the corpse in one piece from the waist down. As soon as you step into the pants they will stick to your own skin."
