A black v-neck t-shirt and blue jeans are the kind of a fail-safe casual combo that you need when you have zero time. If you need to easily perk up this outfit with a pair of shoes, why not complement this outfit with a pair of black suede desert boots? This one is a viable choice when it comes to picking out a well-coordinated ensemble for weird fall weather. Scouting for dressing ideas for men in their 40s? This combo should go straight to your inspiration folder.
