In high school it was a drag, people just want to be different at that age and set themselves apart from one another. Now that I am older I can see the benefits of a school uniform. One major part of a school uniform that I find to beneficial is quite the opposite of the point above, it means everyone looks the same, and therefore can't be judged on their attire. Teenagers can be dicks, and if you or your family can't afford to keep up with the latest trends you may be ridiculed. Enforcing school uniforms removes this problem, schools will often allow you to purchase the uniform through them with weekly payments if you can't afford it up front. All in all I think they are a good thing, and I'm finding it very difficult to think of any down sides.
