My father wore this about 5-6 times. It was purchased from the official Ron Herman online store, so it's definitely authentic. This size seems to be quite rare. My father is 178cm tall and has a solid build. The condition is that there are no noticeable stains, but since I am a layman and this is a used item, I have marked it as "slightly dirty." I am a smoker, so please only purchase if you understand this. Also, I will not do business with those who are overly sensitive or particular, so please understand.
