Thank you for viewing. This is a long-sleeved shirt purchased from a Ralph Lauren authorized retailer. The size is listed as 3, 100 size. The width is approximately 31 cm. Please allow for some error. Unlike girls' blouses, boys' shirts can also be used as outerwear, making them very useful. Of course, you can also wear it as a single layer, and the button-down style gives it a neat look. I don't think there are any noticeable stains, but due to the dark color, there is some fading from washing and use. Please understand this point before purchasing.
