We know, we know - the last thing your winter wardrobe needs is yet another sweater. But hear us out! Among all your crewnecks and turtlenecks is probably a gaping hole where a one-shoulder sweater should be. The slight design change makes all the difference, and we found a cozy option in the Lillusory One-Shoulder Sweater. It's perfect for both running errands and date night. What we love about this one-shoulder sweater is that it marries the best of both worlds. On one hand, it is slouchy and has a relaxed fit.
