I commute throughout the winter. luckily my round trip is only 7 miles. I've only had trouble with my hands in the sub zero temps. everything else stays warm. pain in the neck with the bulky gloves and such, but better than driving, keeps me sane during the cold winters.
I'd recommend specific clothes but I'm not sure if you're going for style points or basic protection from the cold. I usually look like a fool during the winter rides, but my wife just bought me a Descente thermal zero jacket (mine is red), so things are looking up.
cheers
