Make a fashionable entrance anywhere you go in a white dress shirt and a tan trenchcoat. If you're on the fence about how to finish, complete this outfit with black and white leather brogues. This getup is an appealing option when it comes to a killer summer-to-fall getup. As you're moving from your 20s to your 30s, you probably want to start dressing in a more sophisticated manner. That's when getups like this come in very useful.
