I realize it's a biological thing.

I know NO guys who are constantly cold.
But,how do you deal with it?
Top is easy. Layers, sweater. A pair of jeans doesn't cut it though. Wind cuts right through, and I'm freezing. Sweatpants are worse.
Before, I'd just layer more. usually a denim skirt too, or something like that. Point being more fabric covering legs. Does not work now, obvious reasons

Any suggestions?
(obviously not on T =\ In highschool, so is not an option)
