wet-suit type suits be a problem in the US with pools that had strict clothing rules, and the wearers of said suits were not Muslim women but WASP girls (they were a fad for a while) so religion had nothing to do with it.

I am inclined to agree with MissX. Agree or disagree, it is, in their opinion, a health issue, not a religious one. The task of this woman will be to prove to authorities that the suit required by her religion does not violate the health code, not that her clothes should be exempt from the health code on religious grounds.
