This is an oversized open-collar shirt from MUJI. The size is listed as S-M, but it's quite oversized. When measured flat, the shoulder width is 50cm, the body width is 58cm, and the length is close to 80cm. I think it's not an exaggeration to say it's XL. It's a blend of cotton and kapok. Kapok fiber is the down from the kapok tree fruit, and it's very light and has moisture-absorbing and heat-generating properties. It's attracting attention as a material with a low environmental impact. It's an off-white color with a slight yellow tint, and the hem has a box silhouette with a slit of about 15cm on the side. It's a bit thin for this time of year, but the sleeves are wide, so layering with an inner layer shouldn't feel cramped. Please consider it.
