Go for a pared down yet neat and relaxed outfit in a white and black long sleeve shirt and chinos. Boost the classiness of your look a bit by sporting a pair of beige suede loafers. This is a combo you, as a gentleman in his forties, can always rely on.
You'll be amazed at how easy it is for any man to get dressed this way. Just a white and black long sleeve shirt married with chinos. For a more elegant touch, why not complete your look with a pair of black suede oxford shoes? Just because you're over 40, doesn't mean you shouldn't look stylish, and this getup illustrates just that.
