A white long sleeve shirt and khaki chinos are absolute menswear must-haves if you're picking out an off-duty wardrobe that matches up to the highest style standards. Finishing with a pair of white low top sneakers is a simple way to add a fun vibe to your getup. On not so cold days, you can rock this transitional outfit and look absolutely amazing. This combo demonstrates that as a guy in his fifties, you still have a wide array of sartorial options.
