And please dont reply saying 'its magic' because, well..its not.. and dont say they're wearing te clothes underneath cuz shes blaitently not. Any magicians out there..or ex magicians who would share a secret??

Answer 1

They wear the other clothes underneath (folded up/down) each other, all they do then is when the cover goes across them they undo one layer at a time.. It's quiet an easy thing to do, they just make it look good x
