Jones New York sized 8 purple cocktail dress

Jones New York sized 8 deep purple cocktail dress. V neck and long sheer sleeves. Dress zips up back and is sheer but completely lined. The dress is one piece but has what appears to be a sheer “jacket”. I am 5’6” tall and it hits me about mid knee. Very pretty but I just don’t have anywhere to wear it any more. 100% polyester. Dry clean.
