I'm selling this because I can't wear it anymore due to changes in my body shape after giving birth. I am 162cm tall and weigh 54kg, and I usually wear a size M or L at Uniqlo. I think this would probably fit someone who wears a size S. There is a stain on the back of one of the sleeves. Some threads are coming out of the cuffs. The inner label has been cut off, so it's not there.
