80. Side-Part Hairstyle
Once reserved for "Leave It To Beaver" and Dennis The Menace, you no longer have to live in the '60s to rock a side part. Hit the downtown area of any major city and you'll see guys in sneakers and wingtips alike rocking this retro haircut. It adds a classic, clean element to your everyday look, chicks dig it, and it'll make you look respectable to parents everywhere... win-win.
