A blue denim shirt and navy jeans make for the ultimate off-duty look for any modern gent. Put an elegant spin on an otherwise mostly dressed-down getup by finishing with a pair of brown leather chelsea boots. So as you can see, this look is a bright example that good style and dressing warmly for the colder months are not mutually exclusive. Wondering how your styling collection should look as you mature into your 30s? This combo is a wonderful example.
