For the past several years, we've been seeing v-neck cardigans worn buttoned up like a shirt. I layer a v-neck tee underneath here, so I'm not actually going shirtless. Tucking in the tee can also provide a little stomach smoothing. The eye is drawn immediately to the row of buttons and the bottom of the V rather than lower down on the belly. A v-neck also draws the eye more powerfully to the middle of the body than a crewneck. LTKOver40 LTKMidsize LTKSaleAlert
