If you are a big fan of Project Runway, you've heard the term Silhouette; many students have asked what it means when the judges refer to "the silhouette" when discussing a particular garment.
Silhouette shapes are defined by the way in which garments hang or drape on the human body.
Generally a silhouette develops slowly from decade to decade and there are many external factors that affect the change. It is only with the knowledge of what has happened in the past that we can begin to create something new.
