This combo of a navy henley shirt and dark green chinos is undeniable proof that a safe casual ensemble can still look seriously dapper. To bring a bit of fanciness to this look, add a pair of beige suede desert boots to this getup. When it's one of those dreary autumn afternoons, what better to spice it up than a dapper getup like this one? Casual combos for 30-something Millennial gentlemen aren't actually that hard, as you see here.
