If you enjoy functional looks, try pairing a black and white print crew-neck t-shirt with dark green camouflage chinos. You could perhaps get a bit experimental when it comes to shoes and spruce up your getup by rounding off with a pair of beige canvas desert boots. As you can see here, it's extremely easy to look dapper and stay comfy when cooler weather arrives, thanks to this look. This outfit shows how gents in their thirties wow in the style department.
