Well, the Mu Mus get to wear those cool, huge, smock things and that's not fair!
No, seriously, I understand what you are saying now. However, when I was a pledge, we couldn't wear letters. But my roomie, a DG, could. She wore hers all the time. I would think you'd want to because everyone else can't?!? Maybe that's just me.
I've never been a supporter of that "earning your letters" thing anyway, though. I was the type of pledge who put more into my chapter than some of the active members! (And I am sure there are New Members like that in every chapter of every org. at every school.)
