Let's start at the very beginning, always a very good place to start. Everything begins with that spark of inspiration that leads a choreographer to take a piece of music, combine it with a group of performers and create a "new number". As the piece develops the dancers become more proficient, the choreography is fine-tuned but something is missing the costume. I have always felt the costume is the glue that brings a piece together completing the vision, transforming the dancers to characters and transporting the audience into the story.
