As you can see here, it doesn't require that much effort for a man to look sharp. Just marry a dark green parka with charcoal dress pants and be sure you'll look awesome. For a fashionable hi/low mix, go for a pair of monks. During the winter season, when warmth is a must, it can be easy to settle for a less-than-stylish look in the name of convenience. But this look is a shining example that you totally can stay snug and remain stylish at the same time in the winter season. This outfit is probably exactly what you've been looking for as a gent in his 30s.
