Pair a navy suit with a black overcoat for smart style with a clear fashion twist. Finish off with a pair of black leather oxford shoes and ta-da: your getup is complete. In winter, when functionality is a must, it can be easy to surrender to a less-than-stylish look in the name of practicality. However, this look is a clear example that you can actually stay snug and remain equally stylish during winter. As you go into your 30s, you want to start dressing more elegantly. If that's the case, looks like this are perfect as inspiration.
