I saw this movie when I was young so it might be late 90s or early 00s. I saw it on TV when we had Dish. I remember that there was a woman who is a pixie or fairy that can turn into human. When she turns human she is completely naked and goes to a house that belongs to a man with a young daughter. She falls in love with the man who doesn’t believe in magic but has to return to the forest to save her people from the evil man, wizard or something like that. They believe she is dead but she is alive and has decided to live as a human and is now a teacher at the girl’s school. I found the name about a year ago but lost the paper on which I wrote it. I only remember it had a kinda long name.
