Here is a very easy DIY wool coat. I bought the fur for only €15 at the market but you can use any type of fur or wool you like. I did not put in lining yet, since I want to test how warm it is already. Basically the coat goes down straight, so you do not make it any smaller for the waist. You could of course do this if you want to, but you will loose the idea of an oversized coat. I made the sleeves a bit longer so you can tug the excess fabric back in, which makes the sleeves fit tighter around your wrists.
