For an ensemble that's pared-down but can be flaunted in a myriad of different ways, wear a bomber jacket and a navy polo. A pair of white leather low top sneakers is a good option to finish your outfit. Keep this combo ready to go when spring sets it, and we guarantee you'll save a lot of time racking your brain for what to wear on more than one morning. Casual combos for 30-something guys aren't actually that hard, as you see here.
