My apologies to "ss", whose post I misunderstood. I thought the suggestion
was that the fully-clothed dummy would plummet through the trap and a
separate set of empty clothes would be dropped from above.

I think - if I now have it right - the idea is that the man-shaped framework
drops down out of the costume which remains in place, suspended from above.
Then, as soon as the trap door is closed, the costume is released, to
collapse in a heap.

It's an interesting idea, if perhaps a bit over-elaborate, but I'd be
concerned about the visibility of the wires or whatever which support the
costume.

All right, don't use strings. Limit the drop of the framework so that
its head drops no lower than stage level, then supporting the costume
in its 'heap' mode.
