This item was purchased last year. It has been worn for only a few hours, but there is a circular stain about 8cm in diameter on the right knee of the wide pants. There are also faint stains on the left knee and near the hem. I don't know what caused the stains, and there is no odor. I haven't washed it because I wanted to avoid any changes in the fabric's texture. There are no visible stains on the hoodie. There is also some pilling and fraying on both hems of the pants. For those who don't mind these issues.
