This is a size M skirt from index. The color is navy. Please check the length in the photos (approximately 52cm), which would be around knee-length for someone 160cm tall. The waist has some elasticity because the back is slightly elasticated. There is a zipper on the left side. I have never worn it, but it doesn't have the tag. I have tried it on a few times, but only for trying on. The jacket shown in the photo is not included, but you can pair it with your favorite jacket or a cardigan for various occasions. I will sell it to someone who understands that it has been stored at home.
