Arriving in Stepford, Connecticut, Joanna—protagonist of “The Stepford Wives”, a horror novel—is dragged to a “workout class” at the Simply Stepford Day Spa by a neighbour. The duo are met by 15 identikit women. Their hair, heights and skin colours differ a little. Their waist sizes do not. Each can be no bigger than a British size 8, their waists nipped in by belts and accentuated by 1950s skirts.
