I think it’s hard to create an ideal school uniform. First of all, it’s very cold in winter and really very warm in Russia in spring and the beginning of autumn, and school uniform should be perfect for the whole school year. Then comes the question of the materials – it’s of course cheaper to make uniform from modern synthetic materials, than from natural fabrics and wool, but each mother would choose the last variant. At the same time, school uniform should be affordable to each family. If speaking about the design of the ideal school uniform, it should suit every pupil, boy and girl, regardless if he or she attends elementary school or is almost a school graduate.

But I support the idea of school uniform. I like that school uniform is a part of school tradition, and makes you honor your school more. Also I support the idea that pupils should think more about studying, and not about what are they dressed in. Introduction of school uniform can help to ease the gap between the rich and the poor and make pupils treat each other as personalities.
