Dress codes - cool or not?

In my opinion I think that dress codes are a really big nonsense, because pupils don't want to put on the same clothes every day. They can only wash the clothes once a week and then the clothes alwas smell ugly. It looks really awful, when everybody in the school wears the same clothes like you do. I think school codes shouldn't be legal. The pupils should be allowed to wear the things they like. Pupils prefer to go to school with things they want to wear than to have to wear a school uniform. And it looks much better, because there are more colours on t-shirts and so you are in a better mood. You can also see the pupils aren't happy with their uniform, the would be much happier, if the could their clothes for their own i think.
