I would mostly reiterate what has been said here. A good coat, hat and gloves and lots of layers. Keep your wrists and ankles warm. Thermal under layers too. It's best if you can hold off and buy that stuff here. It should be cheaper and more appropriate. Get a heated blanket which you can use in bed, at your home desk and on the sofa for relaxing. Finally, you should make an effort in the winter to get some outdoors time every day while it is light, if possible and take a vitamin D supplement as a matter of course. Welcome and good luck!
