Reach for a polo and navy skinny jeans for an outfit that's both city casual and functional. Black leather loafers are the simplest way to add a little kick to the ensemble. Relaxed casual combinations for guys over 40 aren't actually that hard, as you see.
For a casual outfit, pair a polo with navy skinny jeans — these items go perfectly well together. For something more on the dressier side to finish off this look, complete your look with a pair of black leather double monks. A nice, less conservative pairing for a man in his 40s.
