Who is your favorite vintage movie style icon?

There are so many great icons of style to choose from but I have to go with Katharine Hepburn as my all time favorite. She was one of the first women to wear slacks in public. Katharine had such ease of movement, confidence in every stride that spoke of her complete comfort in who she was as a woman. I believe a lot of her assurance was due to her athletic abilities. She appeared to be at home with a club in her hands. She played golf, tennis, swam, rode and usually did her own stunts in films. 

Naturally, Katharine looked gorgeous in an evening gown or a blouse and skirt but she was mostly herself in trousers, as am I.
