A tutu is a type of skirt worn by ballet dancers, typically made of layers of tulle or other lightweight fabric. It is designed to create a bell-shaped silhouette that enhances the dancer's movements and showcases their technique. Tutus come in various styles, including the classical French tutu, which is short and stiff, and the romantic tutu, which is longer and softer. Tutus are often worn during performances and rehearsals, and they are an essential part of a dancer's costume. The design of a tutu allows for freedom of movement while also providing a visually striking appearance on stage. Many famous ballets, such as Swan Lake and The Nutcracker, feature dancers in tutus, making them iconic in the world of dance.
