When buying a dress skirt two important features you should consider are the shape and size of the collar. The shape and size of the collar you choose is important because it should flatter the shape of your face and the length of your neck to create balance. If you have a long face and neck for example, you will want to balance the length of your face by choosing a wide spread collar with shorter points.
