I have been looking for a very long time - I've tried search engines and quite a few forums - for a film I saw about 10 years ago on Irish TV. Actually, I did not see the whole film but only a part of it. It seems to be American and to date from the 1980s. It is a very slowpaced and psychological movie about a man who dates a woman who might be a werewolf. She has short black hair, a red coat (if I remember well) and definitely black and white striped stocking/pants. She seems to be constantly followed by wolves that she may control. At some stage, they go to visit some of his friends in the countryside where they eat and drink a lot. When she approaches the horses the run away. On their way back, the man stops the car and is sick - it might be due to the fact th she she may have bitten him and he might be transforming. Earlier in the film, for some reason, they are in hospital and start having sex in a closet. She seems to start biting him and he pushes he off.
That's all I remember but I'd love to see that film again. Even though it was very slow, there was something very eery about it.
Are you sure it is the correct title? It also isn't on IMDB which does happen sometimes but still means that it is a very very rare unknown movie. I could find quite a few "She-wolf" titles on IMDB but not sure if this is what you are looking for
