Honestly with a private school it'll depend on if that particular school has uniforms. Most public schools don't, can wear anything besides pajamas, or clothing that shows too much skin.

I go to public school so I wouldn't really know. But I want to say your going to want to find a way to do it while staying in dress code, so just don't violate those things and you will be good. Really though it is school specific, and some schools are stricter than others, so you are going to find out really when you start school.
