Dress with tags

I have 2 dresses exactly the same except for the color. One is burgundy and one is black. The burgundy one still has the tags attached and was never worn, the black one was worn for about 15 mins for a photoshoot. They have a body suit attached and long train with a slit on the side to top of thigh. The brand is Fashion Nova, both are size medium. The top part is a corset.
