Beautiful long tailed white wedding dress

I have a long white strapless wedding dress with a trail in the back with a flower design along the top of the dress and the bottom of the dress. The dress is a zip up in the back but has a button design over it. It pulls up in the back so you can get it off the ground. Bought at David's bridal and only worn once. Was dry cleaned and very faint marks at bottom but barely seen.
