Selling my royal blue prom dress, worn once for a couple hours

I don’t plan to keep it, it’s been sitting up in my closet. Very gorgeous blue dress it has a train in the back, open back, the front is v shape. I got it hemmed because it was to big I’m usually a size 4 but I’m not to sure what the size is on it. But it was still a little big when I had it on. Message me for more details
