In my book, all the characters are dragons. My dragons wear clothes, but only as a matter of practicality. For example, they carry pouches on rope belts to hold their money, they might wear a cloak or cape, they accessorize with rings, and sometimes they wear hats (ones that are designed to fit around their horns, of course. One type of hat is actually two things called horncaps that look like long fezzes that are slipped onto each horn.) The most clothing you'll see a dragon wear is battle armor. Their genitalia aren't externally visible, so they don't have to cover them up with undergarments or anything. It's not unusual for a dragon not to wear anything at all, even though they tend to have some kind of bag on them at all times. Humans use clothes in order to be fashionable or attractive. What do dragons use?
