A Songkok is a truncated cone-shaped cap worn in Malaysia, Indonesia, Singapore, Thailand, and other parts of the world. It is a soft cap with an unstructured crown and no brim. Generally, it is made from cotton, felt, or velvet, depending upon the weather conditions, and is most commonly black in color.
It is a customary hat for Muslim men and is therefore worn on festivals, funerals, ceremonies, and formal occasions. Further, in some countries, such as Indonesia, it is also a symbol of the nationalist movement.
Songkok is known by different names in different parts of the world, such as Peci in Indonesia, Kopiah in Java, and Songkok in Sumatra and Malaysia.
