Style number #RII6. It has an inside corset that can be adjusted by tightening the laced-up backing. Several embellishments throughout which consist of pearls and rhinestones.Has several layers of slip underneath, some are tulle. It has an attached train that can be buttoned up into a bustle. It was only worn for about 5 hrs. I have had this dress professionally cleaned and stored in a keepsake box ever since.
