Combining a blazer and a dark purple cardigan is a guaranteed way to infuse a classy touch into your styling routine. You can get a little creative on the shoe front and smarten up this ensemble by rounding off with black leather derby shoes. During winter, when warmth is paramount, it can be easy to settle for a less-than-stylish outfit. But this outfit is a striking example that you totally can stay toasty and remain stylish during winter. Definitely a nice pick when it comes to style for middle-aged guys.
