Open cross back details. Non-adjustable straps, cowl neckline. Side ruching. This is a lightweight silk charmeuse fabric - 100% silk. Dry clean only. Perfect for a formal event. Very soft material. Only worn once and dry cleaned once. Has a small blemish on the front but most likely easy to clean. Otherwise it is in excellent condition! Wish I could keep it but looking to sell because it no longer fits me.
