How many people here saying the women should have reported it were around in the 60's and 70's? What these women went through would not have even been considered rape at the time. Date rape was not even a concept back then. The police would likely laughed at her and done nothing. At the time, rape was only considered a violent attack by a stranger. And even then, they might have considered her asking for it depending on what she was wearing. If a woman willingly left with a man, then it was assumed she wanted it.
And even if the case went to court, she would have been eviscerated by the defense. "You went into his dressing room, that means you're a slut. You've been with more than X guys, that means you're a slut. You were wearing a skirt, that means you were asking for it, you slut."
