I know she's in there

Our upcoming larp "Mad about the boy" takes place in a world where all men have died. At one of the runs of this larp, we will open for male participants playing female characters. In order for this not to become a caricature, we want to develop some preparatory techniques that will enable men to play women - and not drag queens. We want this workshop to be a test ground and an exchange of ideas on this subject.
