It's impossible to survive winter without a solid beanie. Columbiaknit's cost less than your lunch, are made in Portland, Oregon from non-itchy cotton, and come in a couple of versatile colors. Made on a 1920s-era knitting machine for that extra street cred, you can afford to buy a few—in case you want multiple colors or happen to lose one during a night out. The tightly-ribbed knitting will keep you warm on windy days, while the color fast yarn means they'll never fade in the wash.
