This is a long-sleeved shirt blouse from Samansa Mos2. 100% cotton. Since there is no size notation, I'm listing it as a size M. The color is blue-green, a refreshing color perfect for spring. I retook the photos, so I think the color is now very close to the actual item. It has been worn only a few times and is in good condition, but it has been stored at home, so please refrain from purchasing if you are sensitive to this. Color: Blue系 (Blue-based) Material: Cotton Collar/Neck: Regular Collar Sheerness: None Season: Spring/Summer
