Thank you for viewing. Although the size isn't listed, it's a delicate design, similar to a size 5 or XS. The inside of the gathering from under the bust to the back has elastic. The outer fabric is sheer, and the inner fabric is like silver satin. The neckline is open, so I recommend wearing it with a camisole. I appreciate your understanding of used items. I will fold it compactly for packaging, so please forgive any folding wrinkles. There may be changes between Rakuraku Mercari Delivery and Yuuyu Mercari Delivery.
