This is a Ralph Lauren shirt. The size isn't indicated, so I've listed it as a size S. It was worn by someone who is 150cm tall and weighs 44kg. It felt a little tight, so it would likely fit someone with a slender build as a perfect fit. Also, the back is shaped, which gives a slimming effect. I'm selling it because I no longer use it. It has been stored at home, so there are some fold wrinkles, but it can be worn without issue after washing. I will sell it to someone who understands the above points.
