Untouchables
The Untouchables starring Kevin Costner and Sean Connery is loaded with great examples of hats, suits and many other items from the golden era.

Costner in most of the film wore his hat way back on his head, no doubt because he wanted to make sure everyone saw his prett face.

The extras in the film wear a wide variety of hats and are worth ignoring the stars to look for them in some scenes.

Armani is credited as the costume designer for the film and it shows. Each character his own well defined look.
