I also tend to go for jewelry more than anything else. My staple go-to necklaces are both fleur de lis, and of course I love my badge(s). I also have a modest collectionof fleur de lis watch pins. I do wear blue but not necessarily in a Kappa way.
This should probably go on the "dumb reasons" thread, but one of the factors working against Kappa was the colors. My college was blue & white, most of Seattle's sports teams (Mariners & Seahawks) have blue... so pile on more blue. But whenever I see dark & light blue together I definitely scream KAPPA! in my head. Oh, my poor husband.
For owls, I remember being excited about our wedding location because they had several owl statues. I also have several cute owl things from my travels- Argentina & Peru surprised me with how many interesting owl carvings etc they had. My favorites are some owl gourds- but I love gourds so that's not surprising. I brought back some owl gourds for my Kappa bridesmaids too
