Try pairing a charcoal long sleeve shirt with white jeans to assemble an interesting and modern-looking casual outfit. Take this look in a dressier direction by slipping into grey suede tassel loafers. So if it's a roasting hot summer afternoon and you want to look seriously stylish without putting too much effort, this look will do the job in seconds time. All in all, a good pick if we're talking outfit ideas for middle-aged gentlemen.
