I only put three stars because it runs large. Not a true small. I really wish they had xs. It's too big in neck and shoulders bunch up. The fabric is thick and not at all see through. I like the high neck and half sleeves. The fabric feels soft but also kinda "slick" so some people may not like that feel. For reference I'm barely 5ft and 115 and the small is too big. Not sure if I'm going to keep it or send it back. Price point it is a nice shirt

Comfortable, nice material, looks and feels great. Was thankful that it wasn't overly long. Perfect belly hide but not long
