Speaking of Jeannie and her invisible navel, it was also on the books that Dawn Wells on Gilligan's Island was suppose to keep her belly-button covered according to CBS's SAP. Ironically, sweet, innocent, pure Kansas farm girl Mary Ann Summers wore far skimpier outfits than did sultry, sex-goddess movie star Ginger Grant. But didn't we see Mary Ann's belly-button on the show, and quite frequently? Yes, we did. So how did they get around that? Well, whenever Dawn Wells would wear those teeny shorts, they would constantly slip down exposing her navel and shooting would have to stop, the shorts hiked up, and the scene reshot. After that kept happening, they said to-heck-with-it and just filmed. At other times, they didn't notice it until the episode was edited and ready for airing. By that time it was too late, so they took their chances. Looks like they managed to get away with it.
