cinco de drinko scandel

so in regards to Kappa Sigs Cinco de Drinko party and them getting off campus, i heard a rumor that Kappa were some of the girls that were in maid costumes.
Evidence: couple years ago for Sing, there theme was maids.
I mean, how many groups of girls do you know have maid costumes just laying around???
Coincidence, I THINK NOT
