Kappa - I think the fleur de lis and the blue/blue are super pretty, and it seems like I always see Kappas in letters, which I just love. I also like the single-letter nickname!
Theta - I love that their pansy matches their colors. And again, the single-letter nickname.
Tri Delta - Their pin is really pretty, and it would have been neat to be my older cousin's sister. Oh, and the line from A Southern Belle's Primer... "Delta Delta Delta, can we help ya, help ya, help ya?" Awesome.
AOII - Another cousin is one (we went through recruitment the same year, though), and I think it's neat how they write their pi - II.
DG and AST - I like anchors a lot, and both groups have really nice mottos which correspond to their letters.
