This is a like -new, worn once, black strapless mini dress size small. I cut the tags out, but I believe the fabric is rayon. Item slips on over-the-head or hips and has elasticized waistband and collar. Approximate unstretched measurements are 24 inches at top collar, 22 inches at waist, 36 inches at hips, 28 inches in length. Mannequin measures 34C at bust, 26 inches at waist, 34 inches at hips so you can get an idea of fit of item. Necklace not included.
