It's supposed to warm up a bit, then get colder again. Since I work in a warehouse-like space, I put on layers. Long underwear, knee stockings (thick ones, from Germany), an undershirt, a turtleneck, a sweater, and sweatpants. And if I don't watch it, and sit still too long, I still get cold.
My short, short haircut doesn't help.
But I did make hats - out of fleece. Note to self: take pictures.
