For those of you who think that collar-poppers are poser idiots, the original purpose of that polo shirt was to have that collar flipped upright. Polo players used to wear button-down oxford shirts until they switched to what they now call "polo shirts." The collar was flipped up for two reasons, it actually keeps you cooler and it protects your neck from being sunburned. In the 50s it caught on with golfers who have since turned them down and the fashion world followed them. So for anybody else here that throws them up, let people know why.
