So I'm of the opinion that only jacket collars are to be popped or turned up against rain, wind, snow and cold. Also, once you enter a building or residence down it goes, similar to taking off a hat I guess. I don't see people doing this much anymore or if they have a turned up collar they leave it up all the time. I'm old enough to have lived through the early 2000's heinous trend of everyone running around with the collars on their polo's popped and I see younger guys doing it again now believe it or not. What's everyone's thoughts on this?
