An olive military jacket and black chinos are amazing menswear must-haves that will integrate well within your current off-duty wardrobe. Give a mellow vibe to your ensemble by wearing a pair of black and white low top sneakers. As the weather begins to warm up again, it's time to shed those bulky winter clothes and opt for something lighter, like this outfit here. Overall, a wonderful idea if we're talking fashion tips for men over 40.
