Go Naked In The World (1961) - You'll Be An Old Hag

Playboy Army engineer Nick (Anthony Franciosa) gets the owner of a New York dinner joint (Will Kuluva) to introduce him to Giulietta (Gina Lollobrigida), him not knowing and the viewer only suspecting she's a pricey call girl, early in director Ranald MacDougall's Go Naked In The World, 1961.
