A Kitty Foyle is a dress style of the 1940s characterized by a dark fabric and contrasting light collar and cuffs, typically of navy blue and white. The shape of the dress is a shirtwaist with short or elbow-length sleeves. The buttons of the shirtwaist are in the same contrast colour used for the collar. The style has returned to fashion at times since. The designer Jill Richards, herself a Hollywood actress of around the same era, favoured it in her collections of the 1970s, attracting a clientele of names such as Nancy Reagan.
