I LOVE all the GLOs that have the moon as their symbol (I think it's Gamma Phi Beta and Tri-Delta). I have a tattoo on my lower back with a crescent moon and stars...I've always loved the moon or anything celestial!
I adore Pi Phi's and Kappa's sister pins...they're so unique...and the jewels in them are beautiful. They're just awesome!
I love KD's green and emeralds - that's my birthstone. I've also always felt a connection to KD because my best friend from high school was a KD at UCF (my other best friend was an AZD!).
I admire Alpha Chi's sister pin - as a musician the lyre is a symbol with great meaning for me and something I've loved since I was 3. We had Alpha Chi on my campus but I just didn't fit in with those girls.

But I have a great respect for all Alpha Chis!
I love how most DZ's I've met or chapters I've seen are so service-oriented...it's great that they're so willing to give to others.
