A fascinator is a type of headwear that is often worn at formal events, such as weddings or horse races. It typically consists of a decorative design attached to a headband, clip, or comb. Fascinators can be made from various materials, including feathers, flowers, and lace, and they come in many styles and colors. These accessories are popular in places like the United Kingdom, where they are often seen at events like the Royal Ascot. Unlike traditional hats, fascinators are usually smaller and more lightweight, making them easier to wear for extended periods.
