Phase Eight black sleeveless dress US 10 prom?

Phase Eight, formal dress. It is full length and has a flattering silhouette if you've got some curves. This would be an absolutely gorgeous prom dress. Black with black tape work over the entire dress, and black sequins. V-neck and full back. US size 10 I LOVE THIS DRESS. I wore it exactly once to a formal event. I kept wanting to find something to wear it to again, but it never happened and now it doesn't fit. It was dry cleaned following the event.
