How many schools don't require uniforms in the us?

There is a small number of parents who would choose no school uniform over school uniform.

Most parents prefer school uniforms because:

1) It prevents their children from being late due to the fuss of having to choose and outfit every morning

2) School uniform minimizes school bullying about looks and dress because everyone looks the same

3) They don't have to buy their kids a lot of clothes just so they can wear something different all the time

4) Minimizes the washing load
