Vera Wang Sweetheart champagne Soft fabric unclassified dresses

Hi there, I just bought my brand new wedding dress in may, I bought it in Ohio in a boutique there so I can't really return it. I found a dress that is more my style and I'm looking to sell my other dress. It is literally brand new never ever worn and not altered at all. It's a size 8. The dress is a sweetheart neckline with eyelet fringe along the neckline, it's a champagne colored organza princess style dress, with glass buttons running down the back I the dress with a deep v back and some diamond embellishments under the bust.
