Dress in a white and black polo and dress pants if you're going for a proper, on-trend ensemble. Get a bit experimental with shoes and introduce a pair of black suede loafers to the equation. As the weather warms up, it's time to get rid of those heavy winter clothes and choose an ensemble that's lighter, like this one here. If you're 30, take cues from outfits like this to take a more serious direction in your personal style.
