I am also selling this on Yahoo Flea Market. I'm selling this because I no longer wear it. It has been used, so please understand this before purchasing. The inside is lace, and the pattern looks cute depending on the color of the inner layer. The sleeves are split into two layers, making them fluttery and cool. Material: Polyester (synthetic fiber) Color: White系 (White-based) Neckline: U-neck Transparency: Sheer Season: Spring/Summer
