Why not pair a shirt jacket with white jeans? As well as very functional, both items look good paired together. Feeling bold today? Shake things up by finishing off with a pair of light blue low top sneakers. Keep this getup in mind when warmer days are here, and rest assured, you'll save a ton of time crafting what to wear on more than one morning. And if we're talking casual style for over-30 men, this getup looks nice on most gentlemen.
