I purchased this at AOKI, but the size was incorrect, so I am selling it. It's made of mesh fabric and is non-iron. The inner layer is black, and as you can see in the third image, it's new, so there is no yellowing around the collar. The size is as follows: Neck: Approximately 41 cm Chest: Approximately 52 cm Sleeve Length (from center back): Approximately 85 cm Sleeve Length: Approximately 59 cm Shoulder Width: Approximately 46 cm AOKI Item Number: WK7224F New Price: 5,489 yen (tax included) Reference URL: https://www.aoki-style.com/shop/item/A09_WK7224F
