Monique Lhuillier black cocktail dress

Beautiful elegant dress in excellent condition. Partially lined. Lace over the bustier and lace sleeves. Back zip. Built in bra. Very little stretch. A professional tailor took the hem down about an inch. Lining near the bottom of the dress is starting to pull away from the seams. Easily fixed and not visible when wearing. No material tag but feels like synthetic blend. Check measurements for size. I can't find the size on the tag but fits about a 2 to 4.
