Bowyangs are pieces of cord, rope, or leather that are tied around the wearer's lower legs. A "bowyang" is a single piece of the tie.
Bowyangs come in several varieties:
In England, bowyangs (but not by that name - in Norfolk, they were called Elijahs) were an integral feature of “gorblimey trousers”, baggy corduroy trousers worn by e.g. coalmen and dustmen as featured in the song “My Old Man’s a Dustman” by Lonnie Donegan. In some parts of Scotland, they were known as “Nicky-tams”, and are the subject of a traditional Bothy Ballad of the same name.
