We're loving the way this pairing of a grey suit and a white dress shirt instantly makes any guy look sharp and elegant. You could perhaps get a little creative with shoes and introduce a pair of multi colored athletic shoes to this getup. So if it's an extremely hot day and you want to look seriously stylish without exerting much effort, this outfit will do the job in no time. Wondering how you should dress as you go through your 20s? This ensemble is a great illustration.
