What I do:
First ZERO the figure of cource: but all Morphs applied.
In frame 1 shrink the figure in X90, an Z can go as low as 50%
I leave Y as is.

In frame 10 (keyframe), I set the figure  X and  Z to 100%

=> Check graf that there is no  "overflow" above 100% from frame 10 to 30

The figure-model-doll, (funny how these things get names) Pose I want goes into frame 20.

From frame 20 to 30 I let the cloth "settle down".
