If you don't take fashion too seriously, go for cool and casual style in a bomber jacket and a white v-neck t-shirt. Complete this outfit with a pair of white canvas low top sneakers and you're all set looking smashing. When spring is in the air, you'll love this combo as your uniform for in-between weather. Think it's hard for 40-year-old gentlemen to master cool casual style? This pairing should prove you wrong.
