Thank you for viewing. Please also read the profile. I purchased this in Korea about 10 years ago and wore it a few times before storing it at home. The Korean size 77 seems to correspond to a Japanese XL, but I think it's a tight fit. The collar is removable. There are some loose buttons on the collar. I haven't worn it many times, so I don't think there are any noticeable stains, but there are a few places where the metal parts have blue rust. I haven't attempted a thorough cleaning. Please understand that this item has been stored for a long time before purchasing. I will take waterproof measures and fold it for shipping.
