Katy Perry wowed on the red carpet last month when she stepped out in a vintage Nolan Miller silk dress and a jewelled headband. The Firework singer was certainly channelling the roaring '20s, and it seems she is not alone when it comes to working this trend - which was seen at Gucci's spring/summer 12 shows, as well as on the catwalk at Etro, Chanel and Roberto Cavalli.
"The 1920s look was revolutionary - women were no longer restricted by corsets, and for the first time ever, showed off some leg, although hemline remained below the knee for most of the decade," says Lena Weber, founder of the Vintage Guide to London.
When you're trying to achieve this Gatsby-esque look keep your eye out for drop waists and geometric shapes. The look is pale and interesting - so avoid fake tan, and keep it looking modern with a pulled-back pony and minimal make-up.
