she will hate you later if you give her a real geisha makeup. It takes forever to take off. It is all oil based.
for a simpler version,
use really white fundation, leave the hair line skin colour, leave the back of the neck in some skin colour. anything else can be seen need to be white (not the hands)
pain the mouth bright red and smaller than her real lip. eyeline the top of her eye in liquid eyeliner.
get a wig.
have fun and no one will really know the difference anyway.
