The Schools inspectorate is currently reviewing the case of the Nordic International School in Norrköping, where the pupils must follow a dress code.
This is not allowed, according to the national education agency.
"How people and students dress is a matter of individual freedom and integrity, which are important values in the school. It is also a matter of freedom of speech, which is protected by the constitution in Sweden,"
But Christine Karmfalk, CEO of the Nordic International School, says it is voluntary for the pupils to attend the school.
"We don't force them to wear it, they are here of their own free will," she says.
"The kids that are here, and the parents, they want this. To me it is a question of freedom for them to chose the school they want,"
