A dark green wool blazer and white chinos make for the ultimate smart ensemble. Rounding off with a pair of brown leather derby shoes is the most effective way to bring an added dose of style to your outfit. When the coldest time of the year leaves you with a case of winter blues in the outfit department, this outfit just might fix the problem. So if you need outfit inspiration for dressing as you cruise through your 20s, this getup is an amazing example.
