Was Audrey Hepburn the most sophisticated woman ever?

I think she was. I watch her movies and i just think she looked amazing.
She is one of my all time idol's just because she was classy and sophisticated.
I think Holly Golightly is my favourite ever movie heroine. The reason is simple. Audrey Hepburn gave an amazing performance as Holly. She showed a vulnerability that made me identify with Holly.
Audrey is like Marilyn Monroe in my eyes. A true legend who will live on forever.
