I absolutely adore Audrey Hepburn and when I was a teenager Breakfast at Tiffany's was my favorite movie. Though I felt the male lead was unworthy of the Audrey amazingness. I re-watched the movie as an adult and although Audrey is indeed stunning and charming in the movie the film itself does not stand up as very good to my shrewd adult mind. Nevertheless Audrey remains a style icon for me. She is the ultimate gamine.
Katharine may be slender like Audrey but exuded a powerful personal presence that made her one of the best actresses of her era. I haven't seen quite as many movies with her but find her personal story fascinating. She was extremely intelligent, quick witted and agile in a time where these characteristics were deemed undesirable for women and she pulled it off with such panache. She was very opinionated and did not act the part of how a leading Hollywood actress (she would often dress in men's attire). Hats off to the two Hepburns. Although these ladies both wore wonderful hats as was the custom of the time (speaking of which I found two amazing hats to add to my collection today!) what stands out most even in their photos that makes them fashion icons is not the clothes but their posture, the look in the eye. In Audrey there is a vulnerability of a beautiful, loving person. In Katharine's stance I see something else more dominant, her non-conformity and strength of mind.
