Apparently 40% of your body heat is lost through your head. If this is true, it means that in these cold conditions, it's important to keep your top half toasty. Luckily, today there's a 20% cut on cosy layers. For some tips to working a winter look, take a look at these ladies loitering around Berlin Fashion Week.

Well, if you're feeling brave, make a statement with a wide-brimmed fedora (which works best if you keep the rest of the outfit simple). If not, a trusty beanie will still look ace. Ta-dah! Warm. As. Toast.
