We're not saying that Katy Perry is a bad dresser, but she does wear a lot of looks that could be called costumes.
But that's not the case where these two cocktail dresses are concerned. The "Roar" singer is still far from understated, thanks to the all-over sparkle, but both the Julien Macdonald stunner on the left and gold standard D&G at right have classic silhouettes. We should just celebrate this moment, but it's way more fun to treat it as a one-woman fashion face-off!
