Make a powerful statement anywhere you go by opting for a grey overcoat and black chinos. Complete this outfit with a pair of dark brown suede casual boots and off you go looking awesome. During winter, when functionality is prized, it can be easy to settle for a less-than-stylish look. However, this look is a striking example that you totally can stay warm and remain equally stylish in winter. Wondering how to dress as you slip into your 30s? This ensemble is a wonderful example.
