Popular 1920's Makeup?

There's a "Mystery Dinner" that our drama club does as an end-of-year kind of thing; this year we'll be doing a 1920's gangster themed. I don't know my part yet, so I'm going very basic: what's the general 1920's makeup for a flapper? I've heard too many different versions... rouge, no rouge, mascara, no mascara, smoky eyes, all-around creme wash... Conversely, does anyone know what '20s women who dissaproved of flappers would've worn for makeup, if anything? Thanks in advance!
