School uniforms encourage discipline  Having to wear smart clothes encourages children to respect their school and their teachers and behave themselves. This is because of the association between smart clothes and work. Casual wear at school can also make students feel over-relaxed and 'at home,' meaning they don't focus as much on work. A lot of schools are bringing back school uniform because they want to improve discipline[21].  Moreover, school uniform can actively encourage students to enter into an adversarial relationship with the curriculum and their teachers. Exercising arbitrary control over children in the interests of “discipline” is likely to convince them that the very sensible, rational principles of learning and critical thought that they acquire during the school day are equally arbitrary and meaningless. By refusing to allow children to participate in enjoyable, beguiling processes of discovery and understanding unless they comply with unjustified and meaningless rules about dress, schools risk being seen as oppressive and capricious by their students.  1 The Telegraph, 2009.
