Wanted: Amsale Strapless Gathered Column Gown

I am searching for an Amsale gown--described online as "silk taffeta. Strapless gathered column gown with crystal applique at low hip. Slim flare skirt with chapel length train." The style number is 465. I fit into the sample size 10 perfectly and would love to purchase it once-worn, or a perfect condition sample. I am looking for an authentic Amsale dress--please don`t reply if you are a seamstress or have a
Knockoff.
