Remember when it was cool to knot your tees? Well, that '80s trend may be nothing new, but the way Whitney Port knotted her maxiskirt is. No bells and whistles, but the effect of knotting it up tones down the volume and ups the style factor. It adds a certain nonchalance to Whit's evening maxi and sparkly Vince top, and even a beachy vibe to an exotic print or brightly hued skirt — a little visual interest that simultaneously flatters the frame. Shop any of my maxiskirt picks, then knot it up just the way you want.
