Elle Fanning
The risk-taking teen's psychedelic tie-die swirl print Rodarte dress had our heads spinning, as did her technicolor eye makeup.
Madonna
Looks like the Material Girl forgot a whole lot of material with this bum-baring Riccardo Tisci ensemble that showed off her, ahem, assets.
Katy Perry
We weren't hailing the queen of over-the-top outfits in her Dolce and Gabbana crown and embellished dress.
Mary-Kate Olsen
Sure, the petite designer is known for her boho cool look, but her robe-like coat and deadlock-inspired hair took her signature style a little too far.
Zandra Rhodes
The Brit fashion designer's get-up was more chaotic than couture-like with its out-there combination of tattered fabric, ribbon and chains.
Kristen Stewart

Karlie Kloss
The gorgeous model's Louis Vuitton gown felt like it belonged in a period drama thanks to baroque-like detailing.
Julie Macklowe
The socialite's punky look made us want to riot with its shocking pink shade and one too many spikes.
Gisele Bundchen
Sure, the supermodel has a fab figure, but this skimpy dress looked like one wardrobe malfunction waiting to happen.
