Free People Black Bodycon Dress w/ Low Cut Back

Beautiful black dress with very pretty low-cut back and elbow length sleeves in pristine condition. Dress is fully lined. Approximate measurements laying flat are as follows: armpit to armpit - 17"; waist - 13"; hips - 17"; length - 33.5". Dress is a size medium, but runs extremely small for a medium and would better fit a size small. Dress does have quite a bit of stretch, and should stretch an approximate additional 4" or so, possibly more.
