At around 11:00 p.m. on Sept. 25, hundreds of fans in customized “brat” green outfits spilled out of the Wells Fargo Center in Philadelphia, Pa., still buzzing and singing songs from the 2 hour long SWEAT Tour set. When asked to sum up the show in a sentence, Haverford student Anna Berry playfully described it as “Club music with a side of strip tease.” This description encapsulates Charli xcx’s and Troye Sivan’s incredible feat: a sold-out arena show with the intense energy of an intimate night out that anyone who experienced it will never forget.
