A denim jacket and navy jeans are bona fide menswear staples if you're putting together an off-duty closet that holds to the highest sartorial standards. For something more on the daring side to finish this look, complement your look with a pair of tan work boots. And if you're looking for a kick-ass ensemble that transitions easily into spring, this one fits the bill. Wondering how to master casual looks as you step into your 50s? This pairing is an amazing example.
