Impression Enchanted Disney Collection Prom Dress

This dress is so beautiful, it was like being a Disney princess for a night. I only wore it the one time back in 2014. The bottom look like waves, and it flutters beautifully. I just can't fit into a size 4 anymore, so I don't want it just collecting dust. I originally paid 1,000 for this dress, so it's hard to sell it below 800, but make me an offer.
