Why not go for a multi colored plaid long sleeve shirt and a white crew-neck t-shirt? As well as totally practical, these two pieces look good matched together. Complement this look with a pair of black and white canvas low top sneakers and ta-da: the outfit is complete. So if you're on a mission for a look that's sharp but also entirely spring-friendly, this just might be it. When it comes to casual fashion for 40-something guys, this look is perfect.
