A folk costume expresses a national identity through clothing or costume, which is usually associated with a specific region or 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. Such costumes often come in two forms: one for everyday occasions, the other for traditional festivals and formal wear. The word "costume" in this context is sometimes considered pejorative due to the multiple senses of the word, and in such cases "clothing", "garments" or "regalia" can be substituted without offense.

The Taqiyah, also known as tagiyah or araqchin, is a short, rounded skullcap worn by Muslim men. In the United States and the United Kingdom, it is also referred to as a "kufi", although the Kufi typically has more of an African connotation. Aside from being an adornment, the taqiyah has deeply ingrained significance in Islamic culture, reflecting the wearer's faith, devotion, and sometimes regional identity. While the taqiyah is deeply rooted in Muslim traditions, its use varies based on cultural context rather than strict religious guidelines.
