Formal hairstyles are the kinds of hairstyles you could wear to special occasions like weddings and proms. They come in various shapes and styles, including upcurls, downcurls, upsmooth styles, downsmooth styles, halfup/halfdown styles, plaits and braids. A formal occasion, like a wedding or a prom, requires a hairstyle that is elegant, works with your dress and accessories, and suits your personal attributes perfectly.
