Bands are a form of formal neckwear, worn by some clergy and lawyers, and with some forms of academic dress. They take the form of two oblong pieces of cloth, usually though not invariably white, which are tied to the neck. When worn by clergy, they typically are attached to a clerical collar. The word bands is usually plural because they require two similar parts and did not come as one piece of cloth. Those worn by clergy are often called preaching bands or Geneva bands; those worn by lawyers are called barrister's bands or, more usually in Ireland and Canada, tabs.
