Style Inspiration: Audrey Hepburn in "Charade"

I know, I know - Audrey is a style icon in her own right. She always has, and probably always will, have a huge influence on me when it comes to fashion. However I recently watched the movie Charade for the first time (thanks for the recommendation, Fina!) and Oh. My. Goodness.

The movie itself was fantastic - great plot, fast paced and slick, and the witty banter between Hepburn and Grant is perfection. But the clothes. The clothes! In the opening credits they proudly proclaim that Ms. Hepburn's clothing was styled and provided entirely by Givenchy, so I knew it would be good. But seriously?
Let's just take a look, shall we?

That yellow coat? I die.

I need to go shopping.
