It's size M, but the fit is very relaxed, and since it's cotton, it's comfortable even in the hot summer. The armholes and neckline aren't too wide, making it easy to wear. It's a French sleeve, but it feels almost like a short sleeve when you put it on. I like the muted purple color, which is easy to match, and I've worn it about 7-8 times. The color is almost exactly as shown in the photos. It still seems wearable, but please refrain from purchasing if you are concerned about some wear and tear. Thank you.
