NWT. Never worn. I’m not sure why. I think because I always want to wear shape wear with it but the cut out makes it difficult. Please dance the night away in this dress, it deserves it. Material is stretchy and comfortable. From the website: This is a rib-knit mini dress with cap sleeves, a wide crew neckline and a cut-out detail at the waist. It’s knit with Wonder Yarn — the lightweight yarn that lives up to its name. This peachy-soft yarn offers the all-season warmth of wool, without the wool. It’s made with LENZING™ ECOVERO™ Viscose — responsibly sourced wood-based fibres produced through a process that reduces impact on forests, biodiversity and water supply. This version is constructed using a Fine Rib stitch with thin, compact columns for comfortable widthwise stretch.
