It's wool. The pattern is Morning Mist and I was surprised how rich but subdued the coloration is. I could immmediately appreciate this was hand made. My wife made her own wedding dress...
The fit is generous and you are not cheated by short sleeve length. I mean if it is too long you can always roll up the sleeve, if it is too short you look like a jake turkey. She sewed this so you don't look like a jake.
