Mock or turtleneck pullovers are becoming the new ‘it’ accessory. Layering thin knits under dresses, sweatshirts and light jackets creates a Mod-retro yet contemporary look for next Fall. This versatile base-layer can provide a bright contrast pop, or can be in a similar hue as other pieces for a subtle tonal effect. Details like cropped or slit hemlines, flared sleeves and dimensional ribs freshen up the basic item.
