What are bad things about school uniforms?

Public schools shouldn't issue uniforms because it is a burden on the parents. The parents would have to spend a lot of money buying the uniforms (five for the whole week) and the parents would have to wash them each week because they have five. During the breaks, what would the kids wear? They would only wear their regular clothes for a week, and then go back to their uniform. School uniforms are too expensive for most parents' budgets these days.
