Mischa Barton and Juliette Lewis paired up and partied the night away at the 2008 Cannes Film Festival. Juliette opted for a sexy flapper look (Fab!), and Mischa wore a beautiful silk Roberto Cavalli floral maxi dress from the Spring collection. I love that she took such an exquisite gown and gave it a splash of hippie with the braided headband. Next time you sport a fancy dress, think of ways to incorporate your personality with unique accessories, even if they don't quote unquote, make sense.
