Perceptions of masculinity and femininity
School uniforms are embedded with gender symbolism. Schools that require students to wear a formal uniform almost universally provide trousers for boys and skirts or dresses for girls. Skirts differentiate the female from the male, thereby confirming traditional gender identities for students who must wear the correct attire corresponding to their sex. Skirts and dresses demand a particular type of feminine gender performance, whereas trousers demand a particular masculine gender performance. By forcing students to wear attire that corresponds with their sex inherently assigns the ways a student must perform their gender. This causes controversy when a student does not want to identify with a gender that does not align with their sex. There are rarely guidelines that allow for students to dress according to their performed gender, though almost always according to their sex assigned at birth.
