This is a straw skimmer or boater and was frequently worn in the new version of "The Great Gatsby." These hats were the most popular summer hats of the fashionably in-tune men of the 1920s.

The 1920s come roaring back to life in 3-D this weekend with the 6th film interpretation of F. Scott Fitzgerald’s classic novel “The Great Gatsby.”

Whether you think it is the bee’s knees or nothing more than a load of banana oil, it is a stylistically beautiful hommage to the era’s fashion, which means tons of great hats.

With Leonardo DiCaprio taking the title role, he is proving to be quite the hat fan in our Hollywood Hatties segment. He, like many of the actors in this film, is frequently spotted wearing a straw skimmer, also known as a boater. It looks good on him, too. Gatsby’s rival for the heart of the fair Daisy, Tom Buchanan played by Joel Edgerton, also looks striking in a skimmer.

Toby Maguire, who plays the narrator Nick Carraway, also wears a skimmer, but in this photo he’s wearing an ivy cap. Ivy caps and big apple caps were extremely popular at the time. It wasn’t at all out of place for a man to be dressed in a three-piece suit topped by a cap instead of a hat, especially in the summer months.

There are more hats than these, of course, but these are the heavy hitters of the film. If there is a question you have about an actor in the film and the hat they are wearing, send us a still and we will try to help you identify it.
