The film stars Zooey Deschanel as a rebellious young woman who has a chance encounter with a lonely older man.
Julia hopes the film expresses "how the seemingly simple act of getting dressed shapes one's identity."
The 25-year-old Columbia University grad admits she has been imagining this story for a while but "never in a million years thought I'd be directing."
"Raving" is the first in a series of original fashion based content that the mag has developed for TV, VOD, online and mobile phones.
The film will be available for viewing on Elle.com.
