I say get your normal size you usually wear in shirts. I got a medium when I usually wear a small thinking it might be too short and its not. It is a very soft material. And the floral pattern is very pretty. But because it is a medium, it looks broad in the shoulders on me. But I'm going to keep it and make it work. It can be dressed up or down. And it is lightweight so it will be good for spring and summer. There is no closure, but I have pins I can wear to use to close it if I wanted to. I think it would also be cute with a little belt as well. I got the black one but I want to also get the beige one. I say definitely get this product!
