In layers

This is what I wear to survive 0°C London just to avoid any kind of down coats or jackets. Here I have 5 layers. Long sleeved knit, cashmere vest, wool cardigan, cashmere hoodie (wearing it almost every single day) and wool coat. Because I was so wrapped up like a snowman, I managed to walk out with a just silk scarf for a bit of color.
