A grey bomber jacket and burgundy chinos are a pairing that every dapper guy should have in his off-duty sartorial arsenal. For something more on the dressier end to finish your look, introduce a pair of dark brown suede derby shoes to the mix. Rest assured, this combo will keep you warm as well as looking seriously stylish in this unpredictable fall weather. Definitely a nice option when it comes to fashion for 30-year-old men.
