I've worn these a few times for short periods. I was wearing them to check the size, but they didn't fit, so I've kept them at home since then. They're white, so I looked them over very carefully, but I don't think there are any major noticeable stains. I apologize if I missed anything. ※Additional Information※ I looked up the model number and it came up with the product name listed, but the image showed a different pocket placement on the back. The pants shape seems to be the same, but I'm sorry, I don't know the official product name. Thank you very much.
