For an off-duty menswear style with a modern spin, try pairing a zip sweater with a charcoal crew-neck t-shirt. To give this look a more laid-back finish, why not add white and black athletic shoes to the equation? It's a viable choice when it comes to figuring out a kick-ass look for summer-to-fall weather. Perfect if you're on a mission for some incredibly inspiring style for 20-something men.
