We like this fun blue cover of Confidential from January 1968, but it’s just a bit misleading. The image of Nancy Sinatra is doctored to imply that she's naked. The original, which you see below, was shot around the time she was filming her 1966 comedy caper The Last of the Secret Agents? In the movie there’s a scene in which her dress gets snagged on something and accidentally torn off. The moment is played for laughs, in a public setting. The ensemble she wore in that scene is exactly what she has on in the photo, which suggests it was probably shot to promote the film. Nancy in her undies could not save The Last of the Secret Agents? from bad reviews and an underwhelming run, but while the movie was a dud, the undies photo became quite famous and was used on many magazines, including a cover of The National Police Gazette that we showed you a couple of years ago. Leave it to Confidential to suggest that more came off during the filming of Secret Agents than ended up in the final version of the film, but as far as we know, Sinatra never appeared fully nude in any medium until 1995, when she was 54 years old and did a layout for Playboy. Before that she had shot a promo photo in which she appeared to be bare, but with arms and legs arranged to hide the naughty bits. The Playboy spread, by contrast, hid nothing. And Confidential? It hid the truth.
