What's the problem? Dress codes typically provide that you have to wear appropriate clothing. No tube tops or mesh athletic shirts or short shorts or messages on T-shirts that condone violence or drugs; no clothes that tend to distract from an orderly educational environment conducive to doing schoolwork. Is there some reason you are unable to comply with a dress code of that nature?
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
