Edible underwear is a candy product which is made into the form of, and can function as, underwear, but which is edible.
The product was invented by David Sanderson and Lee Brady in 1975 when they formed a company Cosmorotics, Inc. to manufacture and market the product under the name "Candypants, the original 100% edible underwear". At first the U.S. Patent and Trademark Office denied their application for a patent on the basis that the idea of candy and "pants" were incompatible, but later granted the application and within weeks hundreds of thousands of pairs were manufactured and distributed out of the company's food manufacturing plant in Chicago, Illinois.
