The style of top that you choose to wear with a long skirt depends on the style of your skirt. Long skirts come in a variety of styles. In general a full long skirt looks better with a fitted top and a long pencil style skirt can be worn with a full blousy style top or a fitted top. Usually short women look better in narrow style skirts but tall ladies can wear fuller skirts. It is always a good idea to experiment to see how different tops look with your long skirt.
