This is a very nice shirt. Long sleeves, 3 buttons on the collar. I tend to be medium to tall, this is large and fits perfectly. The material is very soft, 95% polyester, 5% elastane. It says fleece lining, I think it's a layer, not too heavy but not flimsy either, the perfect weight for a cool summer, late spring, early summer day. Whatever this material is, it's very, very stretchy! I could imagine that I could put one more person in the shirt, the arms would easily stretch out twice as long. But they return to normal form after their release. It's unlike any other shirt I've ever worn. I expect a lot of use from this really beautiful color. Can be worn under another shirt or alone and looks very pretty.
