Rock a white and red plaid long sleeve shirt with blue ripped jeans for an off-duty outfit with an edgy twist. And if you want to effortlessly amp up your outfit with a pair of shoes, complete your look with a pair of dark brown suede desert boots. Stick with this one if you're on the lookout for a solid summery outfit. Casual combos for stylish men over 30 aren't actually that hard, as you see.
