To don a casual getup with a clear fashion twist, pair a navy long sleeve shirt with olive chinos. Feeling adventerous? Shake things up by sporting brown leather work boots. In winter, when warmth is key, it can be easy to surrender to a less-than-stylish ensemble. However, this ensemble is a good illustration that you can actually stay toasty and remain equally stylish in winter. This combination demonstrates that well into your 30s your dressing options are in no way limited.
