Uniformity.
One of the most obvious advantages of wearing school uniforms is the fact that all students would look the same. Those who do not have sufficient means to buy fashionable and expensive clothing can surely benefit from this, and parents can also save a bit of money from not having to buy trendy clothes for their children. Aside from these perks, school uniforms shows a form of unity at the school, wherein students wear the same outfits that give them a single identity that distinguishes them from other schools.
