Tops & Flops: The Week in Fashion

Does Jessica Chastain's refreshingly minimalist approach to dressing make you cheer, or is this stark white Alexander McQueen dress too severe?

Was Marion Cotillard a vision in Dior, or was her black ball gown a total bore?

Is Jane Fonda's age-defying body the talk of the town, or do you hate her bronze Atelier Versace gown?

Is it admirable that Charlize Theron clearly has no fear, or is this Christian Dior dress inappropriately sheer?

Are you feeling the heart-shaped hole in Zooey Deschanel's chest, or does she need to give her "adorkable" style a rest?

Is a cleaned-up Ke$ha the one you love the most, or does she still look gross?

Did Kristen Stewart's Marchesa dress create the right kind of fashion stir, or did the dress overpower her?

Are you loving Freida Pinto's bedazzled top, or is this a flashy fashion flop?

Is this an unquestionably beautiful dress, or a hot mess?

Beautifully over-the-top, or does she need to stop?

The week in fashion included the start of the 65th Annual Cannes Film Fest, where the stars went all-out to look their best. Whose couture gowns ruled, and who got schooled? You decide!
