Emma Watson and her Bling Ring co-stars have been quite busy promoting their movie at the Cannes Film Fest this week.

All four young starlets wore their best day dresses for the photocall session the other day. Emma chose a beautiful twofer dress from Christopher Kane, while Katie Chang chose a striped number from Jill Stuart’s fall 2013 collection.

On the other hand, the other two cast members chose to wear dreamy white pieces.

Claire Julien opted for an uber-exquisite Balmain Fall 2013 creation — another two-piece that knocked our socks off. Taissa kept it perfectly demure in a prim white confection from Alberta Ferretti, a Fall 2013 pick.

Now, among these four pretty young ladies, who do you think had the best look at the photocall? Whose outfit deserves two thumbs up?

Claire and Emma may not be wearing dresses, but we’d like to include them here anyway. So, whose look is your favorite?
