To assemble an off-duty ensemble with a modernized spin, dress in a white crew-neck t-shirt and white jeans. Add beige suede casual boots to this ensemble to avoid looking too casual. Keep this getup ready to go come spring, and we promise you'll save a ton of time planning what to wear on more than one morning. Think it's hard for over-40 guys to master cool off-duty style? This combination will prove you wrong.
