I opened the preservation box to see that the interior tags say it's a Jordan Couture Collection. It is a true, U.S. size 14, cream with a sweetheart neckline, a lace-up corseted back, and a separately purchased cream sash with beading on it that matched perfectly. I'm about 5'4" and I wore a beaded barefoot sandal. No alterations were done to it.
I must also disclose that it was a beach wedding as you can tell from the photo on the beach. It's been professionally cleaned, however the cleaning results indicator on the preservation box is listed as “good” and not “excellent”. I have opened the box and inspected and did not see any visible sand stains on the bottom of the dress or on the crinoline (see photos I took).
I am happy to sell both the dress and sash as-is and cover USPS Priority Flat Rate shipping (within the U.S.) for $105 total.
