Formal hairstyles are elegant and sophisticated hair arrangements typically worn for special occasions such as weddings, proms, or formal events. These styles often include updos, braids, and sleek ponytails, designed to complement formal attire. Accessories like hairpins, tiaras, or flowers can enhance the overall look. Common formal hairstyles include the classic bun, which is a neat twist of hair secured at the back of the head, and the chignon, a low bun that adds a touch of grace. Other popular options are French twists and half-up, half-down styles, which provide versatility while maintaining a polished appearance.
