Undy-thesia

Akin to a phantom limb but goofier this is the sensation that you are wearing underwear when in fact your skin is bare. Heightened by lack of sleep or laziness in self-care, your skin begins to feel like a barrier of cloth. As tactile hallucinations it is equally harmless and lacking in value.

Undy-thesia sets in a few days after you stop adhering to certain standards of dress. I surprised myself and a homeless man while riding my bike in a skirt into the wind. He gasped, "Oh, thats beautiful!" Like brushing your teeth and not farting in public, put in the effort to maintain certain standards. Treat yo' self.
