Cardigans are very necessary as the weather gets colder. READ: Seriously Stylish Winter Coats For Under $100 We love them for layering, wearing over a soft tee or button-upped blouse, and under a blazer and warm winter coat. They’re a great alternative to a pullover or turtleneck, especially in offices where you’ve got no control over the thermostat and are at the whims of a computerized heating system. Button them up in a colder moment, button down when the office is warming up. And sling them over your shoulders when someone’s managed to crank the heat up to truly unbearable levels (it happens, doesn’t it?) And when the weather warms up, you can wear ‘em in place of a coat. You know the drill. Here, we’ve rounded up 10 cozy cardigans— some more fitted and preppy, others a bit more oversized and loose-fitting — to keep you warm all winter. The great thing? They’re all super-affordable, clocking in at $50 or less. See below and start shopping!
