GU and Undercover collaboration pajamas. Size is M. As shown in the photo, the right elbow area is white. I think it's probably bleach. Also, there is a stain on the right back pocket, but I don't know what it is. I don't think there are any other stains, but there is a possibility of oversight, so please forgive me if there are any. I am selling it at a low price because of this. This item has been stored at home. Please refrain from purchasing if you are looking for a perfect item.
