The term 'BALLERINA outfit' is composed of two words: 'TUTU' and 'BALLERINA'. A TUTU is a type of ballet costume, usually made of tulle or netting, that is worn by female dancers. It is typically short and has multiple layers of fabric. The BALLERINA is the female dancer who performs classical ballet. She wears a TUTU as part of her costume, along with other items such as a leotard, pointe shoes, and tights. Together, these items make up the traditional BALLERINA outfit.
