Katy Perry rocked a star-spangled look while hosting a Get Out The Vote concert in Philadelphia, Pennsylvania, that was perfectly patriotic!

The "Rise" singer wore a custom Prabal Gurung creation on Saturday that riffed on Hillary Clinton's now-iconic preference for pant suits, while still being very Perry with a sequined stars and stripes mini included in the ensemble. TheCalifornia native completed her look with Joan Hornig white gold earrings, bold blue eyeshadow and a fierce red lip.
