That looks like a ballet costume the kid did not want to take off after practice.
Kids usually start dancing in the Nutcracker in the role of a rat. It's the right period of the year for rehearsals...
Well, yes, but rehearsals are just rehearsals - I'm not sure that they'd be rehearsing full-dress in October, or even if the costumes are even ready yet. (I have a five-year-old who does ballet.)
On the other hand, it could be another performance which is happening now.
