I am obsessed with this shirt! It is the perfect over shirt. It can be worn multiple ways, I chose to wear it open and over another long sleeve turtle neck in the picture. It is soft and semi-thick, so perfect for layering or worn as is. The buttons are plastic, but made well. They aren't really heavy because of being plastic instead of metal. There were no loose threads or cheaply sewn seems. I got a small and it fi really well, looked slightly oversized but not too big. It is so cozy and nice I can't wait to get more in different colors.
