Pair a navy trenchcoat with a beige plaid suit for a proper refined menswear style. For something more on the daring side to finish off this ensemble, introduce a pair of brogues to the mix. When leaves change color and autumn is at its best, you'll appreciate how great this ensemble is for awkward fall weather. If you're wondering how you should dress as an over-50 guy, this pairing is a good source of inspiration.
