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.
