This is demonstrated in film "Mean Girls" when the new girl in school, Cady Heron (played by Lindsay Lohan,) is given lessons on how to fit in by the popular crowd, dubbed the "Plastics". Cady had just moved to town after living and being home-schooled in Africa for most of her life. Having not been exposed to socially-constructed feminine norms, she showed up to school wearing casual, gender-neutral clothing. When she was invited to sit with the popular crowd, ring leader, Regina George, complimented Cady. Regina told her that she thought that she was pretty, but said so in a somewhat surprised tone, as if to say that despite Cady's clothing, she was attractive and because of this fact, she should be dressing in more of a feminine fashion. As Cady spends more time with the Plastics," she states that it is like stepping out of the real world and into girl world. This "girl world " is a prime example of gender being construed into a process where certain feminine standards and norms are to be upheld in order to form a distinguishable difference between sexes. .

             In the film, in order to be able to sit at the lunch table with the group, each girl must abide by certain clothing rules: one could not wear a tank top two days in a row, no more than one pony tail per week and the color pink must be worn on Wednesdays. If the dress code is broken or if one of the girls wears an outfit deemed unacceptable, she would be forced to sit and eat her lunch at another table. According to Judith Halberstam in her writing titled "The Bathroom Problem"", these rules are examples of activities which "police gender. In order to fit in socially, males must present themselves in a masculine manner and females must do so femininely. Lorber explains that "in social interaction throughout their lives, individuals learn what is expected, see what is expected, act and react in expected ways, and thus simultaneously construct and maintain the gender order.
