GUNNY SACK DRESSES
A lady looked all over a dress shop in Glen Ellyn, Illinois, for something that she liked and could wear. Her final selection startled the proprietor and gave her a new idea. The customer purchased a gunny sack that was covering one of the mannequins during the period between seasons! The dress shop began offering the gunny sack dresses to other hard-to-please customers as well. And it became a fad in the early 1970s.— Encyclopedia of 15,000 Illustrations
