I'd totally go for Cate Blanchett in " I'm not there" . The androgynous look that contrasted with the long, manicured fingernails was so hot.
I also think the model Freja Erichsen is really attractive with short hair. I love slightly androynous looking people.
Like Yanna I also have a crush on PJ Harvey, but I think that is mainly because of her work.
Edit: Can't believe I forgot the gorgeous Marlene Dietrich:
She was so attractive!
