The video for "Break the Rules" finds Charli and her team of Heather-like girlfriends doing, what else, but making some trouble. The clip is set in a nihilistic present where graffiti and dress code violations are the biggest form of rebellion and young girls have no problem hijacking a school bus, which soon becomes their discotheque.

Charli and her bad girl posse take a break to go shopping at a trashy vintage store that looks more like a Frederick's of Hollywood. There are no "Fancy" moments here. Like Cher Horowitz would be caught dead shopping at a vintage shop named "Trashy." As if.
