It's a Bikini World (1967)

Yet another fine film in the beach party genre. This time, there is no Annette Funicello, but a certain Deborah Walley. She actually wears a bikini, so I'm of the opinion that she is a bit more suited to this kind of thing. Oh, and she plays a feminist. The layers, the depth.

Here's another strange thing: imdb lists The Big Lebowski as a beach-party movie. I must have blinked during that part of the movie, because the only beach I remember is the one where they scatter Donny's ashes. Am I wrong? No, I'm not wrong, I'm just an asshole.
