It's made from Brooks Farm Mas Acero (wool/silk/viscose) and I had heard that it grew when soaked. Boy, did it! But that's okay - it's really about the length I thought I wanted it.
I'm really happy with it -- it's nice and soft and except for one wonky button hole, I think it turned out great!
Sorry about the crappy picture, taken in the restroom at work. I don't really have a mirror at home that works for this. Of course, I'm not sure how well the staff restroom works, either!
