The Blonde Bombshell (1999)

Diana Dors (Hawes) poses in a one-piece swimsuit for a room full of men with cameras. One of the men says other models pose nude and asks if she will if they pay her extra. Dors hesitates, looking nervous. Then she agrees, smiles and walks away. She comes back in a robe revealing cleavage. Then she removes it. The men start taking photos. We see her butt and side of her left breast. It may be a body double because she has slimmer hips and smaller butt than Hawes.
