I purchased this several years ago, but it was unused. However, it developed some stains during storage, so I hand-washed it. (See image 4) The stains are mostly gone, but the characteristic luster of silk seems slightly diminished in those areas. The fabric is tightly woven, and you can feel the crisp texture of silk. The stitching on the inner neck tape and the (likely) shell buttons indicate careful construction. 80% silk, 20% cotton. Originally priced around 20,000 yen. How about it for spring?
