I love sweater dresses. I never understood them, since where I grew up it was always too cold for a sweater dress until I moved to Alabama. Then I realized that places where it normally doesn't get below freezing are perfect for sweater dresses. (Of course, this winter has been freakishly cold here. Today the high is 30, I think.)
Sweater dresses and fleece leggings are the best! Just not on zero degree days like we've had lately. At least in New England, we expect winter weather. Your Alabama neighbors must be having a hard time with the cold!
