During spring/summer, one of the smartest things you can do for yourself and your image is to keep your dress shirts a lightweight cotton, or even more breathable linen. But to offset the nature of the material, make sure your tie is a substantial one. We recommend an inexpensive wool knit by The Tie Bar. And as always, make sure you get that dress shirt made-to-measure; they cost as much as ones off the rack! You’ll be the most comfortable guy at the office and still look like you’re all business.
