Vintage keyloun halter black satin gown

Says size 10, is actually about a size 6? I wore this once to a Hollywood themed party as seen in the last pic but it was too big and long for me unfortunately :((( I am 5’3” (barefoot in the pic but it was still too long in heels) and usually a size 2/4 in dresses. Not sheer at all and in fantastic condition. I wish this fit me so bad because it’s absolutely my type of dress!! Black tie vibes
