Natasha, I know the Carrie Hoodie is a very popular piece. I tried it on in the store, and while its a very nice piece, be advised that it is a lot more casual looking than the shak, and made from a rougher scratchier feeling weave. In terms of sizing, all they had was a medium in charcoal with a thistle stripe, and it did layer very nicely over my small thistle shak without feeling like it looked too big. I didn't buy it cuz I wanted pieces that would go from work to cycling. While a nice piece, I didn't think I could do either with the carrie hoodie.
