I've lived in MI my whole life, and we get a ton of lake effect snow. I agree with the poster above, that if you keep your extremities warm most days you can get away with a sweatshirt and a North Face fleece over it for your torso. Keep your feet, hands, and ears warm and dry and you will be fine! The weather is an adjustment, but winter can be absolutely breathtaking in it's own clean, white, fresh way!
Seriously, buy some gloves (I always wear the cheap kid's style cotton ones for ease of washing, gloves get gross touching outside stuff) and keep your hands stuffed in your pockets while you walk outside. As for feet, buy some waterproof boots (I do the Uggs simply for function, I think they are hideous and always have, but they do keep your feet dry and warm) that go above you pant line. While walking outside, stick your pants into the boots, then when you get inside pull them out and let your jeans fall normally. No one notices you have on ugly shoes if you untuck your pants to draw the attention away from them. Nothing sucks more than your pants to get all snowy and wet and having to sit in class all day like that...ick. As for ears, I just pull my hood up on my jacket and call it good. I don't really think earmuffs or bands are necessary unless you are going out to stay out, ie build a snowman or ski or something. Knit hats are good too, but as a girl they really mess up your hair and it's too hot to just leave them on once you get inside.
