Unlike most hosiery, tights are opaque rather than sheer to provide total coverage from foot to waist. Full coverage comes in handy during colder months and when you need to disguise bruises, scrapes, or stubbly legs. The nearly endless array of colors and patterns of tights allow you to be creative as you complement skirts and dresses. Control-top tights provide additional support to keep your stomach tight and some also help lift the bottom. Choosing the correct size is imp... moreortant to prevent the tights from rolling or sagging.
