The gown is from the White by Vera Wang Collection. It is designed with hand-cut bias organza. It is fully-lined and has a hidden zipper.
This gown was taken in at the waist and chest and a slight sweetheart neckline was added. It has a full train (modern cathedral-length--62" from waist), though I only wore it bustled because I like how full it became.
The photos attached are of me in the dress. I'm happy to send you more of my dress or I can send you photos from the Vera Wang ads of the same gown.
