As for this GORGEOUS ruched, twisted,  viscose bodycon dress by none other than DONNA KARAN, it's JUST TOO DARN SPECTACULAR !!!!!!!!! It's a BRILLIANT DAY/EVENING dress with the most wonderful expensive style and made of viscose/ spandex , ALSO, IT IS LINED- double-faced, so no bra necessary-- I LOVE the genius material, I call it memory stretch, which just plays it up perfectly!!!!
The style IS-- BEYOND -- with a genius twist of fabric, and amazing material, hiding any imperfections . It has just a tiny bit if spandex to compliment the already super stretchy material, but the material is not too light weight, AS NOT to show all the imperfections, because it is lined, it is a medium weight , it SCREAMS HIGH-END!!!!!!!!!!!!!

Being couture Donna Karan, it's spectacularly well-made, with couture-quality seaming and attention to detail !!!!!! It is -- COMPLETELY AND UTTERLY a Magcial Piece!!!!!!! The condition is great, no significant wear.
The size is XS. there is no size or  composition label, made of viscose and spandex, and the lower layer looks like silk. The size is represented by the measurements ,
