I only wore a uniform for middle school, and while everyone hated this fact, I do think it's great to have during that time in one's life. Everyone's so self-conscious as it is, it was relieving for me to be told what to wear so that I wouldn't have to wonder if my clothes were "cool" or "sexy" or whatever. We weren't made to wear skirts though, I wouldn't have been able to tolerate that, I think.
