I bought this a few years ago. I think it's in good condition, but I've used it about 10 times. Please refrain from purchasing if you are sensitive to used items. This is a long type from the popular Balloon series. It's incredibly cute and has a see-through feel, so it looks great with leggings or denim. I remember buying it for around 12,000 yen. Measurements (laid flat): Length approx. 90cm, Waist approx. 33cm I think it's probably a size M. I don't know how to read Adidas sizes, so I've included a photo of the size tag for reference.
