I think that The Great Gatsby has had some influence on contemporary dressing. I'm seeing more boyish haircuts and drop-waist sheath dresses.

The hats of all eras thrill me. People don't wear them anymore. So when you see an outfit completed by a hat (that's for men too) it's thrilling. Especially if it's a Cloche from the 20's or a Peter Pan from the 30's, a Homburg from the 50's, or a Stingy Brim from the 60's. It's time stamping. Today everybody just wants to wear a baseball cap!
