A really preppy school for girls who may have lesbian tendencies, but are actually not gay. All of the students there go to college, except for Josie Maran, who is a supermodel. The uniform consists of a short blue skirt and blue or white polo. Castilleja girls obsess over most guys they meet, and very few of them are ACTUALLy gay, despite rumors.
Mark: that chick is hot
Jake: yeah, she goes to Castilleja
