My Aritzia stitch coat was a lifesaver on this trip. Very very warm. Technology and quality to support -4F. I’m in a medium. And it’s on sale for a limited time. Linking the Aritzia beanie and mittens too. Underneath? Just lots of layers. Cashmere. Air essentials luxe. Waterproof Chelsea boots. The sidewalks got quite slushy and the boots are holding up great!
