I purchased this when in Japan at a consignment store. So, I do NOT have any original receipts, but I am confident it is authentic. the price will allow Postmark to authenticate. Previous owner was very respectful to the bag. This thing feels worn once or twice. It still has that new bag smell. It’s been sitting in my closet and was only worn once for a dinner with me :( Authentic Comes as a set with dust bag and box.
