This is a fantastic UGG for the cold weather. The knit fabric is very stylish and keeps you nice and toasty! I can wear it mid-calf length, scrunched down, folded over, or open a few of the buttons. It looks GREAT with black leggings and a nice cozy sweater. I probably wouldn't wear this on a heavily snowy day, just because I would be concerned of the snow melting into the sweater and it becoming wet - they aren't waterproof and don't have anything to protect against. But they have already gotten plenty of use!  UGGs are very comfortable, and well worth the investment, this is my 4th purchase of the brand and I am never disappointed!
