 According to the 1978 book "Flesh and Fantasy", Mae West had  stipulated in her contract that only she would be allowed to dress  in black and white in the film. Costar Raquel Welch showed up to  shoot their first scene together in a black dress with an enormous  white ruffle, and West threw a fit. When the films producers sided  with West, Welch had the ruffle on the dress dyed a very, very pale  blue...which ultimately photographed as white.
