Kupiah is a traditional Indonesian cap. It has two shapes, and therefore, there are two types of kupiahs, Meukeutob and Riman. Riman is much simpler as it is a conical, cylindrical cap whose diameter keeps on decreasing evenly as it gains height. Meukeutob is slightly different; it has a similar declining circumference, but it has a sharp visible decline after a certain height, similar to an hourglass. Beyond this, the circumference increases a little.
At times, Kupiah Meukeutob is worn at an angle, but it can be worn straight also. Kupiah is made of colorful beads forming a pattern, and the head band is decorated with lace. It is a daily-wear hat but is mandatory in most official and ceremonial events.
