OLD: How the…. Magic? Quick changing performers…

I am absolutely baffled how this couple does this! I know this is an old video so if you’ve seen it… good for you, have a cookie. No, not really, I was being sarcastic! Give me my cookie back! Basically the idea is that they change their outfits faster than you can blink. My Theory? I think they’ve just created an interdimensional portal with cloth that allows one girl in an outfit to step out of another dimension each time they conseal her temporarily. Makes sence right?
