Petites will look better in a mock neck sweater than a turtleneck because it's far less bulky. There are a couple reasons petites might want to wear a mock neck sweater--to disguise a crepey neck or to keep warm in cooler weather. Petites can create the look of a flattering V-neckline by layering a thin V-neck sweater over the mock neck sweater. This basic mock neck sweater is available in petite/small through petite/extra-large sizes from Macy's ( Buy Direct).
