READ: The front of the envelope calls this a trapeze dress, but it does not fit the common definition. The sleeveless dress has a fitted waist. It only has a trapeze look when worn with the overblouse.
Historical Context Note: This pattern is a quintessential example of how American pattern companies adapted the avant-garde "Trapeze Line" (introduced by Yves Saint Laurent for Dior in January 1958) for the home sewist. By making it a two-piece ensemble, McCall's allowed the wearer to choose between the radical new "swing" silhouette and the traditional cinched-waist look that had dominated the early 1950s.
