I purchased these at an archive vintage clothing store for 30,000 yen. They are no-mass-prod denim pants. They are made from two denim pants, one on the inside and one on the outside, and I really like the unique details. They are one-of-a-kind and won't be found on anyone else. As you can see in the 5th photo, they were made in the 34th week of 1996, making them quite rare. They can also be used for the currently trending darkwear style.
