Davids Bridal Wedding Dress

White wedding satin drape dress, never worn, brand new with tag. It fits women regular size 12 but the dress size states 14. At Davids bridal they fitted me and said wedding dresses must be different size than our regular clothing due to the materials etc. it needs to be sent to the cleaners Since its never been worn and in the storage bag other than that its in perfect condition. My weight has changed to a size 7
