We love the way this smart combination of a grey plaid blazer and white chinos immediately makes you look on-trend. Black leather double monks will infuse an added touch of refinement into an otherwise too-common getup. This one is a viable idea when it comes to putting together a standout outfit for unpredictable fall weather. You can take cues from getups like this if you're in your 30s and you want to take a more mature approach to your personal style.
