This smart pairing of a double breasted blazer and a denim shirt is extremely easy to put together without a second thought, helping you look awesome and prepared for anything without spending a ton of time searching through your wardrobe. In the colder months, when warmth is a must, it can be easy to surrender to a less-than-stylish ensemble in the name of practicality. But this ensemble is a bright example that you can actually stay toasty and remain equally stylish during the colder months. When it comes to dressing ideas for 20-something gentlemen, this outfit looks great on most men.
