In 1942, McCardell created her famed "Popover Dress". It was a response to a Harper's Bazaar challenge to create something fashionable one could wear to clean the house and then, wear to a cocktail party. The simple grey dress came with a matching potholder that fit into the dress pocket. The "Popover Dress" sold for $6.95 and more than 75,000 were sold in the first season alone. These dresses became a staple of McCardell collections and over time, she made versions in different lengths and fabrics. The "Popover Dress" received a citation from the American Fashion Critics Association and in 1943, McCardell won a Coty Award.
