What is a mock-neck jumper? I hear you ask. Well, let’s start with what it’s not. A roll-neck (or a turtleneck, as they’re known in the U.S.) typically has just that—a roll neck, a portion of fabric on the neckline that folds back on itself to create a double-layer effect. Most roll-necks sit under the chin, even when doubled over. Of course, thicknesses vary, and you can choose whichever one speaks to you. Still, generally, I find a large percentage of roll-necks come up too high and feel somewhat suffocating on my petite frame—especially the fitted iterations. As for my bust? I feel like the height of roll-necks doesn’t do my curves justice. Irrational as this may sound, I have spoken to other women with bigger busts who, although we can’t put our finger on why, just don’t love wearing roll-necks. Enter mock-neck jumpers.
