The document discusses the four main components of fashion: silhouette, color, texture, and details. There are three basic silhouettes - straight/tubular, bell-shaped, and back bustle. Color is usually the first thing noticed about a garment. Texture refers to how a fabric feels and is influenced by fibers and construction methods. Details are the finished characteristics of a garment like necklines, sleeves, and trimmings that can be altered to make noticeable differences.
