NWT Windsor white mini dress

Super cute, new with tags V-neckline tank shoulder dress. Sheer mesh panels on the back, and a mini-length, curve-hugging silhouette. Size XS. . For size comparison I am 5'6 and 100lbs, the XS is a little too big for me. See in last two photos on me. It would fit better on someone who is a small or XS/Small
