We love cardigans at Her World, especially if they are long, loose and black. Get one each in a neutral hue and bright shade. The only details: the buttons. Silk cotton jersey blends are soft and most flattering. Check out Uniqlo +J. For work, wear a cardi in red or indigo over a neutral shift or a ruffle blouse and printed full skirt. For evenings, layer one in a contrasting colour over a strapless dress or LBD. For weekends, a gray cardi smartens up a tank top and rolled up khaki shorts.
