Knowing the shape of your body, knowing what looks good on you and what doesn't is basic to dressing well. For example, if you are petite and curvy, it is better to avoid long dresses or maxis, even if you like them a lot. Instead, you should go for a dress that defines your waist better and is just above the knees. It is not about limiting yourself to one type or cut of clothing. But if you know what looks good on you and how you can take advantage of this to see yourself much better.
