When it comes to high-octane class, this combo of a navy quilted gilet and charcoal wool dress pants never disappoints. And if you want to instantly tone down this look with footwear, why not add dark brown suede desert boots to your outfit? Can you see how super easy it is to look stylish and stay cozy when cooler weather arrives, all thanks to looks like this? Certainly a great choice if we're talking fashion for gentlemen in their 20s.
