Katy Perry's Americana Outfit: Who Makes the Stars and Stripes Stunner?

You're lookin' truly superb in stars and stripes, Katy! The oh so patriotic Perry made sure to flaunt a red, white, and blue stunner to her concert on the 4th! An appropriate ensemble for KP to rock on America's birthday, right? We're not sure if KP and JM made it a point to match, but does it really even matter if they did do the whole planned (maybe couple) matchy-matchy thing? We're just loooooving the fact that they both chose to get festive during their stay in the city of brotherly love.
