While we just broke down the fashion selections of Whitney Port and Audrina Patridge at last night's MTV Movie Awards, here we have a showdown in sparkles. Katy Perry gave us a preview of her music video “California Gurls” with a nude, sequined dress, yellow nails and blue hair. Somehow it works because it's her. Meanwhile, Lindsay Lohan scored an invite somehow, and went retro in a plunging, ombré beaded Pamella Roland jumpsuit with waist-grazing blonde tresses. A perfect choice to cover up that ankle monitor, but we're not sure who's going on with the eyes, girl. Who do you think wins this fashion clash? Vote below! Who looked better at the MTV Movie Awards?
