school uniforms
Uniforms are held to a specific standard when they are given to the school for reuse, just as if you were donating clothes to the needy. Children will not receive uniform that are stained or worn down, they have to be in a moderate shape. Kids at public school wear spandex to school and ill fitting clothing that isn't appropriate to wear to school. If the school isn't strict with their dress code, then children will be able to dress more freely.
