The zoot suit was from the late 1930s and the 1940s, not the twenties. The film Casablanca was 1942.
The twenties, of course, is famous as a period of prosperity and wild living in the US. Unfortunately, it ended with the election of Franlklin D. Roosevelt in 1932 and the Great Depression, which he caused with his Communistic policies. I hope that is not an augury for the election of another Communist (Obama) and another Depression due to the imposition of Communist policies on the US.
To Heck with politics, I like hats, and not the baseball variety.
Nothing wrong with a good looking hat.
