As you can see, looking on-trend doesn't take that much work. Consider wearing a navy blazer and a cable sweater and you'll look incredibly stylish. Want to dress it up with shoes? Add a pair of black leather loafers to the equation. When it's one of those gloomy fall afternoons, what better to spice it up than a dapper outfit like this one? You can take cues from looks like this if you're working your way through your mid-20s and you want to take a more mature approach to your style.
