To look like a true dandy with a great deal of class, pair a white and navy plaid blazer with khaki dress pants. Finishing with dark brown suede casual boots is a simple way to inject a more laid-back feel into your getup. If it's one of those dreary autumn afternoons, what better to brighten things up than a stylish look like this one? Outfits like this have a refined air that suit gents in their forties really well.
