Cayce knows, for instance, that the characteristically wrinkled seams down either arm were originally the result of sewing with pre-war industrial machines that rebelled against the slippery new material, nylon. The makers of the Rickson's have exaggerated this, but only very slightly, and done a hundred other things, tiny things, as well, so that their product has become, in some very Japanese way, the result of an act of worship. It is an imitation more real somehow than that which it emulates. It is easily the most expensive garment Cayce owns, and would be virtually impossible to replace.
