In 1962, the
Victoria Racing Club, faced with waning crowd attendance at racing events in Victoria, Australia, added a "Fashions on the Field" competition to the program for the
Melbourne Spring Racing Carnival races held at Flemington Racecourse. The competition was intended to woo female racegoers in particular. Three years later, in 1965, textile manufacturer
DuPont de Nemours International engaged Jean Shrimpton, then the world's highest-paid model, to travel to Australia to be a judge in the 1965 "Fashions on the Field". Her fee for the two-week visit was , equivalent to in , an enormous sum, corresponding with at least a year's wages for the average Australian man. Even
the Beatles had been paid only £1,500 for their tour of Australia in 1964. During the four days of the 1965 Spring Carnival events at Flemington, namely Derby Day,
Melbourne Cup Day,
Oaks Day and
Stakes Day, Shrimpton would be promoting
Orlon, DuPont's new
acrylic fabric. DuPont sent Shrimpton rolls of Orlon so that she, in conjunction with her London dressmaker, Colin Rolfe, could design a secret wardrobe for her visit. Her visit to Australia was highly anticipated She also later told ''
The Australian Women's Weekly'' magazine "I always wear my day dresses above the knee." == Derby Day ==
