This is a T-shirt I bought in Korea. Material: 95% polyester, 5% polyurethane When the shop staff wrote the price on a piece of paper on top of the clothes I purchased, some of the magic marker got on the shirt underneath. I didn't notice it when I bought it, and it was put in a bag and given to me, so I only noticed it after I got back home. The two black dots on the back of the neck are from the marker. I couldn't go back to Korea to complain... I've been wearing it as is because it's hidden by my hair. I haven't been told about it by anyone else while wearing it. It seems to be made for distribution in Japan, as the tag has Japanese quality labeling. The size is free size. It's made of stretchy fabric, so it can be worn by someone who usually wears a size L, but the silhouette is quite defined, so I think it's better for those who are slender to medium build to wear it for a more relaxed fit. The fabric is easy to wear and feels smooth. There's a snag in the seam on the right shoulder. It's not unraveling, so I think it won't be very noticeable if you pull the thread to the back. I will fold it up small enough to fit in a Yu-Packet Post Mini envelope and ship it.
