Everything in this world has already exist, as a knowledge, haven't observed by human beings, and own clothes is just another possibility of something that is probable of discovery.
example of why I said that proverb--> Thomas Eddison didn't create light bulb, but he discovered it, as a possibility.
Another example would be--> a proverb that I "created" might be the same as someone else, which one can conclude that one merely discovered it as someone else did.
