This is a rare beige shirt-outerwear released a few years ago by Shun Oyama when he launched SO. It's meant to be worn as an outer layer over an inner garment, rather than as a standalone top. It's made of a slightly thick material. I think it can be worn as an outerwear in spring and autumn, and as an inner layer under a coat in winter. Marked size: M The size has a slightly loose feel. Below are Shun Oyama's comments regarding the size: "As a size guide, I, Shun Oyama, am 164cm tall and weigh 53kg, and the M size fits slightly loose. For people of average build, M would be the appropriate size. For those with a chubby or muscular build, or those over 173cm tall, the L size would likely provide a better balance." *Since the product is no longer listed on the official website, it may be difficult to understand the wearing image and texture. I have worn it twice, but there are no noticeable stains. Please understand that this item has been handled by a person, so please purchase only if you can accept this. No returns or exchanges.
