An olive camouflage field jacket and white chinos worn together are a perfect match. Rounding off with a pair of dark brown leather derby shoes is an effortless way to infuse an extra dose of elegance into your getup. When leaves are falling down and fall is setting in, you'll appreciate how perfect this outfit is for in-between weather. This getup proves that as a middle-aged gent, you still have a vast array of dressing options.
