Thank you for viewing. The size is 70. My son, who was born in the fall, only wore it a few times, and it has been stored at home since then. Basically, there are no noticeable stains, but there is some yellowing on the white part of the collar. I think it might come off with washing... Please purchase with the understanding that this is used clothing that a child has worn. Please refrain from purchasing if you are sensitive to this, to avoid any trouble...
