I'm wearing sweatpants and a light jacket, and I'm indoors and still freezing. I don't think we have the heater on though; we usually don't during the day for some reason. I probably should put on something heavier, but I don't like blankets or my coat... they're too bulky and cumbersome :/
Of course, once we do start up the heater, it suddenly becomes almost tropical inside the house. Go figure.
