I haven't seen that movie but I can remember it's critics from TV... it might be somewhere in the first half of the 90's and movie might be franch (but I'm not sure about that). As I remember clearly is that movie describes a main character's over 200 years long life during which (s)he changes gender. visually, I can remember white curled wigs:) partly, story might be placed in franche revolution (but it might be wrong clue again)
Seams it's finally time for me to see it:) I'll be very thankful if someone can help me.
Cheers!

Orlando (http://www.imdb.com/title/tt0107756/) from 1992 is one possibility.

Yes, that's the one!
Thank you very much!
