Zimmermann's Illustration Peplum merino wool sweater combines a fitted turtleneck with a dramatic peplum waist and optional tie belt. Crafted from 100% merino wool, the sweater features long sleeves and vertical ribbing throughout, delivering luxurious warmth. The high neckline and belted peplum silhouette create a refined, sculptural profile. Worn with or without the tie, it transitions seamlessly from casual to evening wear.
