there was a phase were the models posed on platforms (about 1 foot high, about 2 feet length and width);
In this video https://www.youtube.com/watch?v=EtR_RkBz0to
at 0:58 bis 1:26,
there are several cuts between live models and wooden mannequins, both on this platforms in the same gowns!
I would like to see when the live models entered the room and mounted the bases:
presumably there are no footage or photos of this phase, let alone publicly accessible ones
