This is a ribbed blouson from MUJI. The color is smoky green, and the size is S. I bought this as a spare for the one I'm currently using, but I haven't had the chance to wear it, so I'm offering it to someone who needs it. I am 164cm tall and weigh 55kg, and it fits me perfectly. It can be used in the coming seasons. Please feel free to comment if you have any questions.
