This combination of a red long sleeve shirt and blue jeans is impeccably stylish and yet it's laid-back and ready for anything. If you want to easily up your look with one single piece, why not introduce a pair of brown leather casual boots to this getup? With a look like this in your winter sartorial collection, you'll manage to stay toasty and look awesome despite the below-freezing temps. A good, less conservative ensemble for a man over 30.
