Along my newest project, focusing on the music of the "Roaring Twenties" I'm also in the process of gathering broad information about the period. I read books (such as "Jazz" by Toni Morrison and Wodehouse's Wooster & Jeeves stories) and investigate Art Deco fashion (which by the way was originally a French style and first appeared just before the World War I ).
There is also a television series which hooks me night after night: Babylon Berlin. The second episode introduced us a fe/male performer who was amazing yet another detail really got my attention: the funny banana skirts of the chorus line dancers. Why on earth are they wearing bananas?
Because... there was a very famous Parisienne dancer, entertainer, activist and French Resistance agent Joséphine Baker whose iconic and scandalous banana girdle became the symbol of the Jazz Age in the 1920's!
Now that's quite a legacy!
