A tiara is a piece of jewelry that you wear on your head. It is much smaller than a hat and is usually made from metal with gemstones attached. Brides often wear tiaras when they get married.
Plastic tiaras like the one in the picture are very popular with children who like to play at being princesses.
A turban is a garment you wear on your head that is made from one long piece of cloth wrapped around your head. For some people, it is a religious garment.
