Who: Eva Longoria and Jessica Chastain
What: Two dramatically different blush pink gowns to kick things off on the first night of Cannes Film Festival 2012. Eva Longoria impressed on the high octane glamour front in a show-stopping design by Marchesa (how long is that train?!), while Jessica Chastain let the side down in a cleavage-flashing but relatively low key baby pink gown by Alexander McQueen.
Where: The Moonrise Kingdom premiere, Cannes, 16 May
Verdict: It's Cannes. When it comes to dresses, go big or go home. Eva, we like your style.
