Well, Em was one of the Elsas out there last night but I think we only saw one or two others. But at the girls' school parades there were a whole bunch – both of their best friends were also Elsa. Meanwhile Kate was the only Anna in her regular dress; the only other two we saw all day were in her coronation dress. And the only other Olaf we saw was a fifth grader in the elementary school parade, ha.
At K's preschool Halloween parade, all the girls were 80% Elsa/20% other princesses (I haven't seen Frozen, so maybe they were the other one). I would estimate there were at least 15-20 Elsas. If I wasn't pregnant, I would have done a Frozen drinking game, and done some kind of frozen booze shot for every Elsa I saw.
I saw tons on FB from daycare and school pics, but maybe only one or two out of 40 kids last night? I wonder if lots of kids wore different "outside" costumes last night?
