Kera's favorite pasttime

I enrolled Kera in a dance class for 3 year olds that started in September. She goes every Thursday and she loves it. She wants to wear her dance clothes everyday, and often is wearing her tutu and leotard around the house. Their dance class had a halloween party on Thursday. For halloween Kera wanted to be a ballerina (of course). They were supposed to dress up in their halloween costumes at the party. I tried explaining to Kera that if she came to dance class dressed as a ballerina, it wouldn't look like she dressed up. So she decided to go as her second favorite thing, a princess. Princess Aurora to be exact.
