100% Polyester Purchased the day before yesterday last year. Worn only once. The size is S, but I chose to buy it in S size even though I usually wear M size. It has a relaxed fit. It didn't suit me because it made my upper arms stand out. I might be able to wear something over it, but I haven't had the opportunity, so I'm selling it. Dry cleaned. Please refrain from purchasing if you are nervous about used items. #Dress #Navy ##☆ysss list☆ S size, close to M size
