A tobacco shirt jacket and navy jeans are bona fide menswear essentials if you're crafting an off-duty closet that matches up to the highest style standards. And if you want to instantly amp up this outfit with one item, why not round off with a pair of black leather chelsea boots? As you can see, this combo is a stark illustration that good style and dressing smartly for the winter months are not mutually exclusive. An ensemble like this will help any 30-something gentleman outdo his fellows.
