[Solved] Help with weight paint for walking

Hey! I have my dress mesh and I'd like for the dress to move statically with the rig (meaning the legs won't have any affect on the dress movement). I tried to remove vertex groups related to calves/foot etc, or tried to decrease the weights in general on the skirt part of the dress, but it doesn't seem to work and the mesh started to get glitchy. Are there some useful steps I can perform to acheive the desired movement?


This is the current weight on the skirt part of the dress in a walking state:



here's my blender file for a reference - Blender

Thank you very much in advance!
