I work for a local native American tribal health system in USA and we have an official uniform policy which is pretty standard in that it mentions that men must wear pants, dress shirt and dress shoes. A key difference is at the end of the policy where there is an exception to the degree of "Native dress is allowed if it is appropriate for the wearers culture." I am certain that this is meant to allow for traditional native clothing, but under the wording would it protect me from punishment for wearing a kilt?
