Lisa's wardrobe fashion sense
For fans of LISA AND THE DEVIL and THE HOUSE OF EXORCISM, I can sympathize with your confusion. I've seen both films and am confused myself.
The VHS version of LISA AND THE DEVIL contains the explicit deleted scense enclosed at the end of the videotape. But the DVD version does not have these deleted scenes.
I've watched LISA AND THE DEVIL several times and last night a question occurred in my mind that I never thought of before, but it's so obvious I never thought of.
After Max chloroforms Lisa then undresses her (see the deleted scene in the VHS version) he pulls down her skirt and we see Lisa wearing panties. So, what's so strange about that? Nothing, except that the movie was filmed in 1973 and also, Lisa is a properly, well-dressed classy woman in the movie. She was not wearing any nylons, that is, NO garter belt stockings OR pantyhose. Pantyhose had already supplanted garter belts in the late 1960s so presumably, a female character in 1973 would be wearing pantyhose. I'm up there in age and I remember that no self-respecting properly dressed lady would go out with no nylons (pantyhose) in 1973. I must assume the film's director did not consider it attractive or sexy to portray Lisa wearing a normal item of undergarment common to 1973 - pantyhose, or even garter belt stockings, so he elected to have Lisa go bare-legged. Again, this would be considered a fashion faux paus for 1973, an anomaly. For people who are up there in age like me, jog your memory and recall that pantyhose manufacturers in the late 1960s and 70s encouraged women to wear pantyhose without panties (Americans today call it going, 'commando',lol). I don't think the film's director wanted to portray this in LISA AND THE DEVIL. It would have been perhaps too explicit. And the actress Elke Sommer maybe would have been unwilling to do it even if it was considered acceptable fashion sense in 1973.
