A Costume Designer creates, sculpts and conceptualizes 3 dimensional characters. The big difference between a Stylist and a Costume Designer is that a Costume Designer works off of a Script. The difference between a film & television Costume Designer and a theatre or stage Costume Designer is that the camera comes extremely close and details are important. For stage you have to project past the proscenium and small details cannot be seen the same way they are in film.
