You'll be surprised at how super easy it is for any guy to get dressed like this. Just a grey cardigan and a beige turtleneck. Amp up the formality of your getup a bit by finishing with a pair of dark brown leather oxford shoes. If you're already bored of your transitional season fashion options, this outfit just might be the inspiration you are looking for. A good example for guys aiming to adapt their personal style towards maturity.
