This is an AURALEE 21AW check shirt. I bought it new and have used it about 10 times. It's a very versatile check shirt. The fabric is light and feels surprisingly airy for wool, with a slight transparency. Although it's wool-blended, it can be hand-washed. Here's the official description: WOOL RECYCLED POLYESTER CLOTH SHIRTS 21AW Retail Price: ¥37,400 (tax included) COLOR: Black Check Size 4 (Shoulder width 50cm, Body width 56cm, Sleeve length 61cm, Length 78cm) Please allow for slight variations due to amateur measurements.
