As a petite woman, I struggle to find sweaters that elongate my frame, however, there's one design hack I can always count on to do the work for me. Vertical striped sweaters have that visual magic to create instant, noticeable length - drawing the eye up and down for a taller, leaner look. And whether you love classic stripes or the illusion of them, pieces like ribbed-knit sweaters, cable knit pullovers and striped options are all great for giving your frame that lengthened effect.
