Mori Lee Black cocktail dress, Size 12 but fits like an 8

Size 12, fits like a size 8! Only worn once and dry cleaned, this knee length dress is made of chiffon (polyester), and is fully lined. Sweetheart strapless neckline. It has pleated ruching on the bodice, and a mock wrap skirt. The straps are nowhere to be found, but the bodice has internal boning. No damage, no spots, stains, holes or rips.
