A folk costume (also regional costume, national costume, traditional garment, or traditional regalia) expresses an identity through costume, which is usually associated with a geographic area or a period of time in history. It can also indicate social, marital or religious status. If the costume is used to represent the culture or identity of a specific ethnic group, it is usually known as ethnic costume (also ethnic dress, ethnic wear, ethnic clothing, traditional ethnic wear or traditional ethnic garment). Such costumes often come in two forms: one for everyday occasions, the other for traditional festivals and formal wear.
