I bought this at Costco about 3 years ago, but I'm selling it because button-down shirts are a hassle and I don't wear them. I liked the design so much that I bought it in different colors, and I'm also selling those, so please take a look. The size is S, but I think it's equivalent to a Japanese size L. Even I, at 165cm and 80kg, can button it up even over a thin shirt. The fabric is thick, but it's a stretch material, so it's very comfortable to wear. I've only worn it about 5 times, so it's clean with no noticeable wear.
