The Great Gatsby comes out on DVD this week, and we have an exclusive look at one of the extras, where Jay Gatsby himself — Leonardo DiCaprio — talks fashion! In "Razzle Dazzle: The Fashion of the ’20s," watch DiCaprio talk about costume designer Catherine Martin, while director Baz Lurhmann talks about Gatsby's whole look — and which part of Gatsby's costume was DiCaprio's idea!

Watch the clip after the jump.
