Uniform or No Uniform?

I can assure you that most normal High School students would prefer not to wear a uniform to school. But what are the advantages of wearing a uniform?
Well, good things about having to wear a uniform are:
*not having the stress to choose what to wear in the morning
*no problems caused at school because one girl has something nicer than the other one
*wearing something appropriate
Here in Venezuela most Venezuelan schools use uniforms, not only because they are Cristian schools, but because they believe in a equal society. Which means, maybe there is a girl that can't really afford brand cloths, but her best friend wear brand cloths. In other words, if all girls wear the same cloths, no problems of jealousy or hatred will be caused. Apart from all the pros of wearing a uniform there are always some disadvantages to everything.
Some bad things of having to wear a uniform in your teenage years are:
*not having the chance of expressing your personality with your stile
*trying to break the rules and changing the uniform.
For example I would like to use another shirt that isn't my uniform shirt, but I like it because I don't have to stress out every morning thinking about what I'm going to wear to school.
