What can embarrass a nudist? The answer may be found in “Our Readers Say” column of Popular Science magazine from February, 1938 (page 6).
… a friend of mine …. spent his week-ends giving the mosquitoes a break at a nudist camp, but was greatly embarrassed (if such a thing is possible for a nudist) by the lack of pockets. No mere cigarette holder would have done him any good, for he was a pipe smoker and insisted on having on his person a large supply of tobacco, spare pipes, pipe cleaners, and matches. It was impossible for him to carry around all his accessories with his bare hands. He finally got around the difficulty by getting himself one of these short aprons that carpenters use, with the front full of pockets.
