I used to think some of the things that you do until my children started school at a school with a uniform policy. I used to think that the uniforms stifled individuality. Frankly, the kids just find different ways to be creative - they have unusual shoes, socks and decorate their backpack since none of those things are affected by the uniform policy.
We do have to periodically vote back the uniform policy and it overwhelmingly passes. I personally like the policy. My kids can wear red, navy or white polo shirts with tan or navy bottoms. Pretty simple. I can buy this stuff at Target and resale shops pretty cheaply. They can re-wear last year's uniforms as long as they fit without anyone knowing. The policy is pretty lenient and does not require us to buy uniforms from a certain place..i.e. a $30 polo shirt. It really does make the mornings SO much easier. There is no question about what the kids will be wearing and no question about what is appropriate.
I think kids are going to be cruel about certain things regardless. I don't think that uniforms increase that at all.
