This is a 100% silk vest. The white dress shirt underneath is not for sale. I purchased it from a Chinese online store for approximately 9000 yen. The size is L. I tried it on, but the size didn't fit, so I'm selling it. There are some places where the ends of the thread are visible, but please refer to photos 3 and 4. It doesn't affect the overall image, but please refrain from purchasing if you are concerned about minor details.
