When the occasion calls for a casually smart getup, try teaming a red shawl cardigan with a long sleeve shirt. Introduce brown suede desert boots to your look and ta-da: your outfit is complete. During the colder months, when warmth is crucial, it can be easy to surrender to a less-than-stylish ensemble in the name of convenience. But this ensemble is a vivid example that you totally can stay cozy and remain stylish at the same time during the colder months. So if you're looking for outfit ideas on how to dress as you mature into your 30s, this pairing is ideal.
