“An extravagant swag effect sets Peers’s shapely gold sweater apart. The main fabric, knit in stockinette stitch, is worked in “Stella” from S. Charles Collezione/Tahki•Stacy Charles. This piece tops an airy underskirt and cuffs—knit in mohair “Luna”—that are worked separately and sewn into place. The collar too is knit in “Luna.””
