The songkok or peci or kopiah is a cap widely worn in Indonesia, Brunei, Malaysia, Singapore, the southern Philippines and southern Thailand, mostly among Muslim males. It has the shape of a truncated cone, usually made of black or embroidered felt, cotton or velvet. It is also worn by males in formal situations such as wedding feasts, funerals or festive occasions such as the Muslim Eid ul-Fitr and Eid al-Adha. Songkok came to be associated with Islam in Brunei, Malaysia, Singapore, Thailand and the Philippines, while in Indonesia the peci can also be associated with the nationalist secular movement.
