40+ T-shirts seen at Lollapalooza: Photo gallery

A U.K. MC on Perry's stage shouted repeatedly at one point—perhaps trying to figure out why exactly we were all there in the park in the first place. "We want to learn about music, and we're all individuals," he said. He was on to something. Individualism is perhaps the festival's guiding principle more than anything—but exactly what type of individualism, one wonders. Perhaps those emblems of American individualism, T-shirts, have something to say. Take a look at the tees we snapped and feel free to send us pics of your own favorites—webmaster@timeoutchicago.com.
