I'm undecided. It's kind of cool but I think I would like it better if it was not brown. Too dead animal-ish in brown. I'm not a fan of brown in general though.
I really like the rest of that outfit though. And the other one on the same page is fantastic too.
PS - I think you could knit that hat, Anna! Just have to find a yarn with the right amount of heft. My friend knit a mohawk hat for her son that he wears everywhere.
