Ice and nipples

I am currently researching the studio PR men that created Jean Harlow. It’s an extraordinary story that would make a contemporary star maker blush. Harlow knew the power of her sexuality and manipulated it  to great effect. One of her many tricks to create an entrance  was to put ice on her nipples right before shooting a scene in order to appear sexier. The current wannabes should take some time out and study the old masters.
