Incorrect assumption. A dominant religion in any given society will influence cultural and societal norms. Sometimes, perhaps even more often than not, the reason for wearing religious clothing is social conformity. That doesn't necessarily mean that the wearer is a fundamentalist or even religious at all. There are even atheists who wear religious clothing just because the community they belong to excepts them to do so and they don't want to stand out (applies to all genders). And that's just one of several possible reasons other than the one you assumed to be the only possible explanation.
