Thanks so much for the advice Lisa! Well, it turns out REI is sold out of the Shaks in medium, so I just ordered one in small and will see how it works. I'm still vacillating on the Carrie however — you know, it's just hard to justify spending more to get another cardigan when I've already got one hoodie that I love, and the Shak may meet my needs better anyway. Besides, haven't I sworn off new wool purchases repeatedly over the last year? I've got a deep drawerful of wool (mostly Icebreaker, some Ibex and Patagonia), and there's no way I could wear it all unless global warming gets reversed really soon.
