Other 9WG3838 Long sleeve unclassified dresses

Someone I worked with gave me this brand new dress, her wedding got cancelled after she bought it. She bought it from Davids Bridal. I'm getting married but this isn't the one for me. It's beautiful and isn't altered at all. This has never been worn to an event, there is a clip in the back where the zipper is, the small piece of string it attaches to is torn. I would sew it back if I knew how to, but it can be easily fixed.
