Haley tried to convince Clara to be Elsa from the Frozen Fever short because that dress is gorgeous but she wasn't having it. She insisted on Minnie Mouse which is a much easier costume. The shirt was from Goodwill and just needed the collar to be swapped for a white one. She also had a simple Circle skirt with a double tulle and an elastic waist. The ears were from Joanns.
Since she saved so much time on the kid's costumes she went overboard on her own. Haley and B have been wanting to do Mary Poppins for a while so this was the year.
Note to Haley: Today you said that next year you are reusing an old costume. I know come October 2016 when we are in the crazy place again, you'll change your mind and make something ridiculous but I'm putting this on record, only the kids next year.
