Sweaters range from fine layering pieces to warmer textured knits. Merino wool and cashmere feel smoother and lighter, while Shetland wool, Fair Isle patterns and heavier knits have more texture and a more casual cold-weather look.
Crew-neck sweaters are easy to wear on their own or over a T-shirt or shirt. V-necks leave more of the shirt collar visible and work well for business-casual outfits, while mock necks add warmth around the neck. Choose the neckline according to whether you plan to wear the sweater alone, over a shirt or beneath a jacket.
