over the top sexist imagery in old hollywood films

I've seen cremaster3 recently and the "lamb girls" choreography made me think about those sexist old hollywood films, solely consisting of girls doing cute poses, lying down in circle with their heads pointing at the center and moving their legs to make shapes, or doing figures in a pool, or a single long traveling shot going around and up some giant wedding cake like structure to show the sexy girls planted there in a spiral up to the top. The male gaze doesn't get more blatant than this, yes, the only way to objectify a women more than this would be to glue a handle on her back. I think these were not stand alone films, they were part of "genres"... what were the names of those genres? It's something to be seen to be believed so I want to "google image" these things to scare people. I can't think of anything about it right now... "bathing beauties" was non-concluent in google... What says u?
