Perhaps, maybe they were just jealous of the attention. Many famous actresses at that time and in previous eras did what could be considered "pinup" type work, Jean Harlow, Rita Hayworth, Betty Grable, Jane Russell, among others.
I would imagine any person of breeding would have actually considered a career as a dancer or actress to be low class. Unless one became rich I suppose lol

You're right. Any person of breeding would have thought of the pin-ups as "low class". I doubt Kate Hepburn, Grace Kelly and others of similar breeding were jealous of them. I know the women in my mother's circle thought of them as trashy. The girls lacked the talent to compete with the elite, so they HAD to take their clothes off for attention. That sentiment still holds true today among the young women I know, thank goodness.
