The scarf is often an underrated, underused accessory in man-fashion. The great thing about a well-chosen scarf is that it doesn't just add the right texture and color to your ensemble; it's completely functional in both hot and cold weather!
Obviously, you'd wear a wool or cashmere scarf in the winter, but you can also wear a cotton or linen scarf in the summer. Winter scarfs keep your neck and vitals warm, and summer scarfs protect your neck from sunburn. Smart practicality teamed with logical functionality is always trendy.
