I like this shirt, but not as much as the other PattyBoutik items I have bought. It is very comfortable and flowy. I normally like more form fitted, but I wanted to try a shirt that wasn't so form fitting. The sleeves are horrible for jackets. There is no way of keeping the sleeves from getting bunched up if you need to wear with a jacket. This is a shirt for essentially any time besides cold. It is very thin but not seethrough. It was even comfortable during the summer. Attached I have some pictures showing how it fits on me.
I typically buy M from PattyBoutik. I am 5'1", approx 140lbs, and 34D (although I wear extreme push up bras).
