This is one of the most versatile tops, ever! You can wear it as a sweater, buttoned up. You can wear it unbuttoned as a light card again. Or you can wear it as a top with the bottom buttons undone and tied in the front! No matter how you do it, this one is super soft and unbelievably comfortable! It has a good stretch, too! These run true to size for a roomier fit. Size down one if you want it more fitted. Shown on me in large. 50% rayon, 28% polyester, 22% nylon
