 Five must have winter sweaters. Number one, the errand sweater, AKA fisherman's sweater. Pair it with some brown corduroys and a simple button down for a classic and cozy look. Number two, a seasonal crew neck. Always a great option for casual festive get-togethers with family or friends. Number three, a sleeveless cardigan. Go with some olive corduroys, a button down and penny loafers for some classic country winter style. Number four, a chunky cable knit turtleneck. It's warm, cozy and versatile. Keep it casual with jeans or dress it up with some brown corduroys. Number five, a cashmere v-neck. Yes, it's simple, but upgrading a basic like this to a luxury fabric is a decision you will never regret.
