I think you should get the gray sweater in a different style. I vote for the gray sweater wrap (the one in the middle) Super cute.

I really like the sweater wrap one (the one in the middle) as well. I think that it would keep you warmer, depending on the material, than the other ones. Though if you get more than one get the two wraps like FP suggests.
