Fashion statement.
One that I don't care for....
People can wear whatever they want to wear but I can most assuredly say it's not for me.
MAYBE if you're a national touring pro and are on payroll for a company, and in that case MAYBE.
I don't see it as "cool".....
Since there are so few, it is my subjective OPINION that if you wear one you're a loser (figuratively speaking) and pretty much everyone thinks that except those wearing one....
Cue: "but your shoes say Dexter....." semantics time.......
