A tiara is a decorative crown-like headpiece, usually made of precious metals and jewels, worn on the front of the head like a headband. Unlike a full crown that circles the entire head, a tiara is open in the back and sits forward, often worn for special occasions like weddings, formal balls, or beauty pageants.

Throughout history, tiaras have been worn by royalty and nobility to show their rank and status. When you see photographs of European princesses at formal events, they're often wearing family tiaras passed down through generations, some containing diamonds and gemstones worth millions of dollars. The British royal family owns dozens of historic tiaras, and wearing the right one can signal both the importance of the occasion and the wearer's position in the family.

Today, brides sometimes wear tiaras on their wedding day to feel elegant and special, even if they're not royalty. Young girls might wear simple tiaras as part of dress-up play or costumes. While the word strongly suggests something fancy and feminine, a tiara at its heart represents that universal human desire to mark important moments by wearing something beautiful and extraordinary, something that announces: today is special.
