This seriously stylish ensemble is so simple: a short sleeve shirt and jeans. For something more on the classy end to round off your outfit, complete your outfit with brown leather casual boots. In this, any over-40 man is bound to put many a younger man to shame.
Consider teaming a short sleeve shirt with jeans, if you want to dress for comfort without looking like a hobo to look dapper. Feel uninspired with this outfit? Invite a pair of dark brown fringe leather loafers to change things up a bit. As you can see here, in your 40s your dressing options are in no way limited.
