Uniform codes are rules or regulations that tell people what they can wear. They are like a dress code that everyone needs to follow. For example, if you go to school, your school might have a uniform code telling you what kind of clothing you must wear. You might need to wear a school shirt, pants, or skirt, and you could be asked to wear a different type of shoes. These rules help everyone follow the same standards and make sure no one is wearing something inappropriate.
