I am tall and thinner and this shirt is actually gorgeous. I'm 5'9, 162lbs and I got a xl. It's a nice longer tunic length, sleeves are a great length even on my long arms. It's so soft, perfect lighter-weight sweatshirt. It IS lined, however with a thin liner. Not fleece or anything too warm or thick.I washed it by itself on delicate in cold water and hung to dry. It dried perfectly smooth and soft and kept it's shape 100% ��
