Two of the sororities on my campus do this--Phi Mu and Kappa Delta. The KD's wore theirs like on their bras or something because the fraternities would steal them from them. I don't know, we didn't really have an issue with that. I thought, that wearing that ribbon was SOO important. If I would forget to put it on and realize it when I was outside of my classroom, I would walk back to my room and put it on even if that mean I would be late. I guess I have always been a little enthusiastic about this whole Phi Mu thing
