Don't dismiss something until you have tried it. And when temperatures plummet, try doubling your sweaters. I paired a thinner turtleneck sweater with a thicker sweater to keep warm (it's quite windy here). I did not want to wear just another button down under the sweater. Honestly, it's very difficult to tell if I'm wearing one piece or two because the turtleneck is the same color as the top part of the sweater. It was one of the most comfortable work outfits I have ever worn. 

Also try layering a cardigan over a sweater, Jessica Day style.
