Grace learned the first design line to look for is the silhouette. It’s the outside line of any outfit, and is the difference between the shoulders/waist, waist/hips and hips/shoulders. It comes in two categories: angular and curved. A silhouette is angular when the shoulders, waist and hips appear to be the same width. On the other hand, a curved silhouette is when the waist is significantly smaller than both the shoulders and hips.
