Ok. mods- I think we need to split this convo.
Unfortunately, the circumstances I refer to are not "standard dancer no undies"
In particular, I refer to a recent situation in which the script calls for an actress to lay down with knees splayed as an actor looks at and comments on her "area". On the day we were first supposed to rehearse this scene, we had to stop and wait for actress to go out her car, into her gym bag and dig out some panties, because she had neglected to wear any that day (in a skirt).
