The Fashion Club, dating, shopping, being cute, cute animals, popularity, parties
Quinn, Daria's sister, centers her life around her good looks and pursuit of boys. Her self-centered attitude annoys Daria, leading Quinn to tell everyone at Lawndale High that they're cousins, not sisters.
At Lawndale High, Quinn a member of The Fashion Club, constantly pursued by Joey, Jamie and Jeffy (the three Js), as well as most of the male student population, and from day one has been one of the most popular girls in school.
Quinn is constantly squaring off against her arch-nemesis: Sandi, the Fashion Club president. They compete for the attention of boys and for popularity as well.
Though Quinn appears to be brain-less and ditzy, in several episodes it's suggested that she's intentionally dumbing herself down to mask her insecurity about being a "brain".
