Aladdin's tasseled hat is commonly referred to as a FEZ, which is a three-letter word. The FEZ is a traditional brimless hat that originated in the Ottoman Empire and is still worn in some parts of the Middle East and North Africa. It is usually made of felt and has a tassel attached to the top. The FEZ is often associated with Aladdin, the main character from the popular Disney movie of the same name.
