A tutu is a type of skirt that is often worn by ballet dancers. It is typically made of multiple layers of tulle, a lightweight and sheer fabric, which gives it a fluffy appearance. Tutus come in various styles, including the classical bell-shaped tutu and the more modern dancer's tutu, which is shorter and more fitted. Tutus are usually worn over a leotard and are an essential part of a dancer's costume for performances. They are designed to allow freedom of movement while enhancing the visual appeal of ballet choreography. The tutu has become an iconic symbol of ballet and is recognized worldwide.
