To look clean and dapper, marry a white and blue vertical striped dress shirt with beige dress pants. Our favorite of a myriad of ways to complement this ensemble is a pair of dark brown suede tassel loafers. Keep this combination in your front hall closet when warmer days are here, and we promise you'll save a ton of time brainstorming for what to wear on more than one occasion. If you're wondering how you should dress as a 20-something guy, this combination gives a fair idea.
