Armeture for cloth moves the cloth out of place

I have sculpted pants for my rigged character. They fit perfectly. But when i parent them with my character and transfer the vertex data to the pants, they jump slightly out of place.

Pose is set to “clear all” and I already did “apply all transformation” to the pants.

a blend file ll be welcome if you want to be helped.
