OK, but what should Alexa wear to daycare?

Daycare is having a Fall Festival tomorrow, which is basically the PC way to refer to a Halloween Party! We heard that some of the kids dress up in costumes. But Alexa gets her daycare clothes so dirty that I didn't want her to mess up her football dress before her big day! So... What to wear? We had a little dress-up session tonight... Ballerina? Pink skeleton? Stay tuned to find out what she chooses!
