Navy & Black/Silver sequined/beaded floor length mermaid style formal dress

So much to say about this dress. Navy background with black and silver beading and sequins throughout the entire dress. Fully fitted to the thigh when it flares out into a mermaid style. Fully lined, pads in the bust-line and tulle in the bottom flare to make it stand out. Spaghetti straps, v-neck and back zipper. This dress was worn once as a costume. It as a placket in the back which concealed a mic and brace or for modesty. It can be removed/cut out to reveal a deep back plunge. Tag states it is an XS, however I am a size 6 and it fits perfectly so this probably runs large for an XS.
