Silk
Put thread in the mouth of a worm while the moon is out and it will poop out some silk. That's why they call them silkworms, didn't you know? But it has to be while the moon is out, otherwise normal thread will come right back out the other end of the worm. The moon is what makes the magic happen.
Picture feeding some thread into the mouth of a worm as the light from the full moon shines in on you. See the silk come out of the worm's butt and into your hands.

Wearing silk is the key (き) to not being nude (ぬ). Wear it!
Picture yourself wearing nothing but silk. Silk shirt, silk pants, even silk underwear. It feels great against the skin! And most importantly, you're not nude.
