Lets start to focus on the bottom half of your body. You don’t want this freezing weather to effect your whole entire outfit you had planned to wear if it was only 20 or so degrees warmer, so why not invest in a sexy pair or tight polyester/cotton pants or dress pants? These are very casual, but will keep you very warm. You don’t want a cold bottom, do you? Pants that are tight on the body, which guys like if you didn’t know, will keep your body heat in, and that freezing air out. Perfect!
