Do lay Buddhists ever wear distinguishing clothing or jewellery? I'm aware that Buddhist monastic communities often wear robes that distinguish them and visibly mark them out as Buddhists. Do lay Buddhist ever do the same thing? Is there any jewellery or clothing that lay Buddhists wear to mark them out as Buddhists - a visible marker of their religion. This is obviously common in other religions e.g. crucifixes for Christians - but do Buddhists of any tradition have an equivalent?
At least in the Theravada tradition people do not were distinguishing clothes or jewelry.

Though not used as a distinctive form, but as more of protection and a good luck charm, some wear a Pirith thread.
