I wore white pants in winter. Call it "winter whites" or whatever you'd like. I like how it looks, but my legs were definitely cold. White (summery) jeans leave a lot to be desired in the warmth department. However, this sweater is plenty warm, especially with a chambray underneath. So, my top half was plenty toasty, and the bottom half a wee bit chilly.
