NWT Formal gown with train size small

This stunning gown was purchased new and altered from a 12 to a size 6. Then the event was cancelled so I never got to wear it. Zipper back closure with hook and eye behind the neck. There is a small area of missing sequins in the back (as shown) but there are extra sequins attached to the tags. Measurements are: length is 70 inches in the front (not counting train) bust is 35”, waist is 27”, and hips are 35”. Dress is fully lined in the front and back with both sides being transparent from top to bottom. This dress is HEAVY. Purchased from a formal/bridal boutique.
