Most great dresses have all of the following characteristics: 1. Balanced proportions on a flattering fit. 2. An element of intrigue via print or embellishment. 3. A hint of comfort, physical or emotional, but preferably both.
Valentino provided many examples of such dresses in their Resort 2013 collection. The understated elegance of the dresses drew the eye to all of the right places (and help minimize the other ones), giving simple shapes equal parts structure and ease.
