A blue long sleeve shirt and khaki chinos worn together are a good match. A pair of brown leather boat shoes looks perfectly at home teamed with this outfit. Can you see how super easy it is to look sharp and stay toasty come chillier days, thanks to this getup? As you're going from your 20s to your 30s, you want to start dressing more maturely. That's when ensembles like this are a safe option.
