School Uniforms
I don't think school should be treated the way you would a job. This is a crucial time for young people to develop their sense of selves. While I do agree you should present yourself professionally in a work environment, not all jobs adhere to such strict dress codes, I don't think school should be one of the places that does. & as for conforming just to you, most schools do have a dress code barring showing of midriff, shoulders, and thighs. As long as you're covered, I think you should be allowed to wear casual things, like jeans & t-shirts
