This is a party hat all covered in gold. Party hats are most often in the form of a cone. They are usually made from a piece of thin cardboard with designs printed on the outside and a long string of elastic acting as a chin strap running from one side of the bottom of the cone to the other to secure the cone to the person's head. Party hats are often worn on birthdays or for example New Year celebrations. Hats of other shapes are also worn, which can also indicate the informal and festive status of the event, for example decorated plain hats or hats made of balloons. A beer hat is another form of party hat where cans of beer are attached to a hard hat with a straw leading the beer from the cans to the celebrant. Regardless of the shape and decoration, the main purpose of party hats is to create a good mood and help people have a fun party.
