tiara

A tiara is a kind of fancy crown or headband that's usually worn by women for special occasions.

You might see tiaras at fancy weddings, formal parties, or even on TV when celebrities walk the red carpet. Sometimes, royalty and other important people wear them as part of their official uniforms or ceremonial outfits. Tiaras are often made with precious stones like diamonds or rubies, which can make them look really eye-catching. Some people also wear tiaras for fun or as a fashion statement – think of it like wearing a fancy hair accessory!
