Alpha Epsilon Phi does not allow anyone other than an initiated sister to wear the Greek letters. New members, significant others, et al can wear shirts that say "Alpha Epsilon Phi" spelled out, or "AEPhi", but not the Greek letters. We waste no time giving our new members bid day gifts and ribbons, but they have to wait until initiation to wear the letters.
A number of NPC sororities don't allow new members to own anything with the crest. AEPhi's new member pin actually
is the crest, slightly modified to remove the Greek letters.
You say tomayto, I say tomahto.
