This is an Asakura party dress. I'm selling it because I don't wear it anymore. The size is 38, which I think is equivalent to a size M or a size 9. The length is just above the knee on someone who is 160cm tall. The color is navy. There is a zipper on the back. The design is cute, and it's recommended as you can wear it stylishly even with just one piece. If you have any other questions, please comment. (^^)
