The wearing of uniform emphasises equality; the fact that everyone wearing that uniform is of the same status, and no-one is “better” in any way than anyone else. I am sure you will agree that this is a good moral to promote in young people. A smart uniform also helps to create pride for the school for its wearers. If children are all wearing the same uniform, they all belong to the same group, which helps to foster a community spirit and ultimately creates a better atmosphere among the children.
