A dance costume is the clothing worn by a dancer when performing before an audience. A dance costume may be custom designed for use in a specific dance work, or it may have a traditional design, such as those used in some ceremonial and folk dances. Typically, dance costumes are designed to harmonize with the dance and not hinder the movements of the dancer.
When created for a specific work, a costume may be designed to expose or enhance the lines formed by the dancer's body, or to express the choreographer's artistic vision, or to engage the audience, or combinations of these. A costume may portray or relate to some characteristic, mood, or theme of the dance. It may fit loosely or it may be form-fitting to emphasize the form of the dancer's body. Costumes are designed in accordance with aesthetic requirements, the anticipated movements of the dancer, and budget. Various people may collaborate in designing a costume, including the choreographer, costume designer, costume maker (seamstress), and dancer.
In the nineteenth and twentieth centuries, Marie Camargo influenced changes in dance costumes by abandoning the traditional corset and dancing barefoot with exposed arms and legs. Later, Isadora Duncan introduced a new look to dance costumes, inspired by the Greeks, of tunics and scarves that conformed to body shape and exposed body lines.
The amount of light a material absorbs and reflects may be a factor in material selection. Also, dance is about movement, so the way a fabric hangs or moves on the dancer is important. Lightweight materials such as silk move faster and easier and tend to flow around the body. Stretchable fabrics such as jersey, silk, chiffon, Georgette, and Lycra are commonly used because they don't restrict movement. Natural materials such as Cotton or silk are typically used when the costume is to be dyed because they absorb dye well. Stiff fabric is typically used to create a boxy, square, or immobile look.
