first at all ,  thank you for your answers, the methods that desccriben vilters and plutom work, in fact I used the vilters method in any occasion , the disadvantage is that it is not as direct as the one I use for conform clothes , because once imported I have to adjust the coordinates "by hand" but it works

maybe  import modified clothing  as morph to  the original ?? , I'll try...

aRtBee thanks for your description of how the simulation works is very interesting and illustrative
