If you're hunting for a casual and at the same time stylish ensemble, pair a biker jacket with grey plaid chinos. Bring an element of refinement to your outfit by finishing off with a pair of black brogue boots. When it comes to dressing for summer-to-fall weather, nothing beats a neat ensemble that can take you from season to season. When it comes to casualwear for guys over 30, this getup looks nice on most.
