In the newest issue of GQ, I came across this pic and I liked the look:
And in the new POLO ads, I have seen the collar pin as well:
You really cant tell from the pic but its being used on a button down collar shirt (without the collar being buttoned down).
Is there a rule as to what collars you can wear the pins with? Also I'd rather not poke a hole in all my collars so i'm thinking a collar bar like the one below is the way to go but I'm afraid that it may...
