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. You can still create a desirable V-line by wearing a jacket over the sweater or layering a thin V-neck sweater over the mock neck sweater. This lightweight AK Anne Klein sweater made from a blend of silk, cotton, and nylon is hand washable.
The sweater is available in black or butterscotch in petites sizes petite - large - Buy Direct from Nordstrom
