Pencil Skirt with Flared HemClassy but sassy, this knee length skirt is made of a silky stretch fabric that creates a smooth silhouette. With a flared hemline that accentuates the curve of the butt and visually lengthens the thighs, this skirt is flattering in any size. Cut higher to sit at the true waistline, you can even combine it with shorter tops and still achieve a smooth silhouette.
