Alpha Chi Omega - I like how AChiO picked their name. (For those that don't know, they were the first to form an org in the school of music (hence, the Alpha) and they thought it would be the last organization of its kind to be formed (there's your Omega). As for Chi, it was changed from "Kai" which means "and".
Alpha Delta Pi - I like that they refer to their members as "Alphas", "Deltas" and "Pis" (NM, Active, Alum) and bonus to them for being the FIRST secret society for women.
Alpha Epsilon Phi - I think this is the only org to have a giraffe as an antional mascot. How very cool! I wonder why this animal was chosen?
Alpha Gamma Delta - SYRACUSE TRIAD! Another great mascot (Skiouros the squirrel).
Alpha Omicron Pi - it is interesting that they are the only woman's org that does not have a crest, they use the red rose instead. Very admirable!
Alpha Phi - SYRACUSE TRIAD! I like that the Phi Bear was anemd after the constellation Ursa Major. ANd they called together the first meeting of NPC in 1902.
Alpha Sigma Alpha - I like that they wear different a combination of different colored ribbons under their badge for special days throughout the year (like Founder's Day and Christmas, etc).
Alpha Sigma Tau - I never knew that AST is an educational sorority (and by the third oldest of it's kind)
Alpha Xi Delta - I like that they have two forms of a NM pin (one for NMs, and another for colony NMs). It shows their apprecition for those girls that colonize a new chapter.
Chi Omega - Very cool that they have a male as one of their official founders
Delta Delta Delta - I thought the crescent moon was only recognized with G-Phi, but I guess you learn something new everyday! Totally proud to share the beautiful crescent moon with you ladies!
Delta Gamma - I like that DG has a nationwide philanthropy event (AnchorSplash OR AnchorSlam) that chapters hold every year. It's very cool to see that each chapters holds their own special version of this event to benefit their national philanthropy.
Delta Phi Epsilon - I like that DPhiE focuses on the internal growth of their org, rather than the external growth by numbers. It shows that each memeber takes an active role in both chapter and alum life
Delta Zeta - I like the creed, the way each member pormises to the world all teh way down to themselves what they will do to uphold the ideals of their org.
Gamma Phi Beta -

'Nuf said!
Kappa Alpha Theta - the FIRST national sorority founded with a Greek letter name, awesome!
Kappa Delta - I like that KD is partnered with the Girl Scouts. (I was a GS from age 5 to 18).
Kappa Kappa Gamma - The fleur-de-lis is absolutely beatiful! And what a fun fact to know Mrs. Campbell was a Kappa!
Phi Mu - The ROSE carnation! The quatrafoil is a very unique symbol, adn it's wonderful that one of your sisters had a play and movie written based on her life. AND you can see a Phi Mu composite in the movie, but you have to look carefully
Phi Sigma Sigma - first nonsectarian sorority, this gives all women of diverse backgrounds the chance to feel welcomed into an org not founded on scripture
Pi Beta Phi - another carnation! It's cool that the angel has become an unoffical symbol b/c of it's popularity among Pi Phis.
Sigma Delta Tau - I like that the rituals were written keeping in mind the different personalities of the founders.
Sigma Kappa - how very cool that SK was founded TWO DAYS before G-Phi. You also have a very unique combination of colors, which allows you to stand out.
Sigma Sigma Sigma - I like that they have a doll collection for every chapter founded and each doll is dressed in period fashions (when the chapter was founded).
Theta Phi Alpha - while some orgs have a petron god or goddess, I think it is unoque that TPA has a ptron saint, St. Catherine of Sienna
Zeta Tau Alpha - who wouldn't want to be a princess and wear a crown! I also like that ZTA adpoted the strawberry in honor of one of their founders who received a basket of them as a gift.
