Give the waist some structure to pull the eye up by adding a belt or sash. The structured styles of the season look great on plus-sized women. Look for a defined waist and be sure to get the size that fits you best - fit is key when wearing a structured shift dress. You don't want it gapping in some places and too tight in others. For petite women, fitted cuts create an hourglass figure and don't overwhelm a small frame, as generously cut skirts and flouncy styles might. Try a feminine cut with ruffles that run vertically to create the illusion of height. Add warmth to any style with cozy tights and boots to top off the look.
