For an ensemble that's absolutely envy-worthy, pair a blue crew-neck sweater with grey dress pants. Let your sartorial credentials truly shine by completing this getup with navy suede loafers. So as you can see, it's a stylish, not to mention spring-ready, combination to keep in your transitional rotation. If you're wondering what you should wear as a 30-something guy, this pairing is a good source of inspiration.
