The current dress coded in place  are discriminating towards women, enforces a outdated policy, sexualizes  children and simply only makes sense in the minds of dictators obsessed with having control of other people. 

You as a child should not be worrying about whether or not your clothes are too revealing for school, you should be focused on your education. The excuse often used is that “revealing” clothes are distracting to the men, which is a horrible ideology to have. Why teach women (mostly) to cover up and not men (mostly) to not focus on those types of things? 

Banning accessories such as hats or belts is ridiculous. They are fashion items, not weapons. No child comes to school with those things in hopes of doing something wrong. Along with baggy clothes, some people use those because of low self esteem or body issues. Schools however do not care about this and want to make people as identifiable as possible.
