Although the size is XS, it fits perfectly or even feels a bit large for me, who usually wears a size M, even when I was 173cm and 62kg seven years ago. As you can see, the string in the back is frayed, so it needs to be sewn. By the way, I remember it frayed when I took a slightly awkward posture. There are also stains, but I think they will disappear if you get it dry cleaned. Please refer to the photos. I bought it for about 30,000 yen at the time, but since the condition isn't that great, I'll sell it at a lower price.
