A navy blazer and navy and green plaid dress pants are a refined combination that every modern guy should have in his closet. For something more on the daring side to complete this outfit, add white low top sneakers to the equation. When it's one of those dreary autumn afternoons, what better to spice it up than a stylish getup like this one? An amazing example for any gent who's still working out how to dress at 60 and beyond.
