The only tag I can find in this one is the small one that says 22 on it.
The cut and "feel" of the dress is your typical Mother's-of style. The skirt is a lined chiffon with an empire waist gathered slightly to the left side. The back has a peek a boo cutout. Below is a full corset closer to allow for a little wiggle room in size. It does lace all the way, but it took forever so I only did id part way in the picture.
