Elie Tahari Navy Sheath Cocktail Illusion Lace Trim Off Shoulder 8

Elie Tahari designer cocktail Sheath dress. On and off the shoulder straps with an illusion lace trim. Deep navy. Sweetheart neckline. Full zip down the back. Lining is made of luxe stretchy satin. Worn once, professionally cleaned. Looks like new! I either can't find the size tag or it came off at the dry cleaner. 95% sure it's an 8. I'm an 8/10 and it fits like a glove.
