Question

How can they change their costumes like that so quickly and before a live audience?

Answer 1

If you look carefully you can see she is wearing many layers already. The costumes must be held on her via velcrose and as she moves she swiftly pulls them away. If you watch the see through purple hoop one the costume is the same colour as the hoop fabric and notice he hooks it over her. There must be a hook at her back that pulls the next costume off her as she pulls the hoop forward. Also, he hands her the green costume, but she is wearing an identical one already and drops it into the bag with the previous dress.

Answer 2
