Rotate Birger Christensen crafts this refined cardigan from a blend of alpaca and wool, defining the silhouette with a structured crew neck, long ribbed-cuff sleeves, and an elegant peplum waist. Crystal-embellished jewel buttons fasten the front, catching light across the compact knit. The soft, finely-textured construction pairs a minimal aesthetic with a sculptural drape, designed true to size for an effortless layer.
