I'm not sure if any other group does this or not. Only initiated Phi Sigma Sigma's can wear our crest. However there is one exception, mothers who are pinned with our mother's pin also can wear the crest since it is on the pin.

As for the colony pins - Phi Sigma Sigma's is a tiny little sphinxhead that we get to keep. It's kind of fun going to our annual conclave and people ask me where they can get the pin. I tell them I received because I was a founding sister of my chapter.

Also, I think Phi Sigma Sigma is one of the few who initiates graduate students as active collegiate sisters.
