“Maru” 丸 means circle. This is a very right weight casual japanese Haori jacket. The pattern is printed.
The haori (羽織) is a traditional Japanese hip- or thigh-length jacket usually worn over a kimono. These lightweight japanese vintage coats are meant to hang open in the front, to better show off the kimono or other attire worn under it. You can wear this vintage haori over a shirt, with pants, or however you want.
