Although it's size 11, I'm wearing a size M. It has darts and looks sleek. The ruffles from the collar to the chest are very cute. The material is polyester, but it's similar to gauze. It has been stored at home for a long time. Please consider purchasing if you understand this. I will fold it up small to send it. Please understand any folding wrinkles that may occur during shipping. #DotPattern #Ruffle #Sleeveless
