And if you need to immediately spruce up this outfit with footwear, why not introduce dark brown leather casual boots to your outfit? If it's one of those gloomy autumn days, what better to brighten it up than a dapper outfit like this one? A no-brainer for gentlemen who are on the lookout for age-appropriate outfits.
