David's Bridal T9612 Lace unclassified dresses

White all-over beaded trumpet style wedding dress for sale from David's Bridal, in original garment bag. Like new, only worn once. Was purchased in 2011. I've included photos of the dress and you can see from the wrinkly train (it's been in the bag) that it would need to be laundered by a professional. It also has a bronzer mark on the inside slip of the dress. Those are the only two issues with it. I also included a photo of a model wearing the dress from online, but the dress I'm selling is in pure white, not beige. David's Bridal lists the dress as on sale for $599 online, so I am asking $200 due to time and condition.
