A charcoal cardigan and a black hoodie are an easy way to infuse subtle dapperness into your day-to-day off-duty fashion mix. Clueless about how to finish off? Complete your getup with a pair of black and white athletic shoes for a more casual aesthetic. We love how perfect this look is when cooler weather arrives. When it comes to casual outfit ideas for over-30 gents, this look looks cool on most men.
