For something more on the off-duty side, wear this pairing of a long sleeve t-shirt and olive cargo pants. White low top sneakers integrate really well within many combos. As you can see, it's very easy to look sharp and stay comfy when chillier days are here, all thanks to ensembles like this. Think you can't pull off cool casual style as you pass the big 5-0? This pairing should prove you wrong.
