Let's review four major categories of men's sweaters: turtlenecks, polo necks, crew necks, and V-necks. Turtlenecks are standout sweaters, known for protecting the neck against cold elements. These tubular sweaters can actually look extremely formal--in some cases, you can wear a turtleneck as a substitute for a sport jacket and tie. Turtlenecks are also wonderful if you regularly participate in outdoor winter sports, like skiing or bobsledding. V-neck sweaters are classic, old country standards. You can wear a V-neck sweater beneath a suit jacket to add formality to your ensemble. You can also mix and match your V-neck sweaters with many items in your wardrobe. Many men's fashion editors recommend that every man own at least one V-neck sweater. Polo neck sweaters are hybrids between polo shirts and traditional men's sweaters. They feature buttoned necklines and raised collars, and they are slightly more casual than V-neck and turtleneck sweaters. The most versatile polo necks tend to be made from pure cotton. Finally, consider investing in crew neck sweaters. These sweaters are far and away the most popular sweaters on the racks. They easily mix and match with a diverse number of other clothing items. You can wear crew necks with T-shirts and jeans or with more formal attire. Additionally, you may want to entertain getting boatneck sweaters. These more cutting-edge items are designed to buck conservative trends, and you should be fully "fashioned equipped" to pull off the boatneck sweater look. For sweaters in classic designs and a range of colors, check out the Gap, Banana Republic, Ralph Lauren, and American Eagle Outfitters. |
