We love how this combination of a navy double breasted blazer and olive dress pants instantly makes a man look sharp and refined. If you need to effortlessly play down this look with one single piece, complete this look with dark brown leather loafers. So as you can see, it's super easy to look awesome and stay comfy when chillier weather hits, all thanks to getups like this one. This combination is your answer to the question of how to dress as you reach your 40s.
