Ok. So to add to my confusion about when to use тысячей and тысячью, I found them used in the same way. And i also found that what there were a thousand of, was used in two different cases. Arrrgh!

So, someone, please tell me....which of these are right? and when do i use which!!!!

женщина с тысячей лиц.
женщина с тысячью лиц.
женщина с тысячей лицами.
женщина с тысячью лицами.

Thanks
