A navy military jacket and beige chinos are the kind of a fail-safe casual combo that you need when you have no extra time to assemble an outfit. You could perhaps get a little creative with footwear and complete your look with a pair of white canvas low top sneakers. So when summer is over and autumn is setting in, you may find this getup your go-to. If you often wonder how to dress maturely while looking stylish, this ensemble is a great example.
