No matter what your feelings about director Baz Luhrmann's new cinematic adaption of F. Scott Fitzgerald's classic American novel The Great Gatsby, you can't deny that the film is generating interest in 1920s fashion. Though reaction to the film itself has been mixed, retailers, fashion bloggers, and magazine editorials all display symptoms of Gatsby fever. Retail collaborations pay homage to the era while also promoting the film. The Great Gatsby, a new collection from Tiffany & Co., features sparkling jewelry designed in collaboration with The Great Gatsby's costume designer Catherine Martin. Brooks Brothers has also introduced new styles based both on 1920s menswear, and the new film version of Gatsby. Though it remains to be seen how much the film and its costumes will affect mainstream fashion, it's interesting to see fashion history encroaching on popular culture.
