i had a charachter wearing short which i converted to a skirt. in doing so i added new vertices/ edited the existing ones.

when i go into pose mode some of these new or edited vertices remain completely stationary, regardless of what the rest of the object is doing. see image below for example.

when i go to edit mode, everything snaps back to a default position so i cant tell which vertices are even the problem. how could i interogate the vertices in the image below to find the problem causers? i know roughly which ones they are but thats not good enough?

also how would you recommend i go about finding the problem here?

extra info: this was object was made with vroid and imported into blender as a vrm. it all worked fine before i messed with it.

edit

in response to the idea of working in weight paint, how could i select and work on the vertices in question in weight paint? You see i have all the vertices in the skirt, as a vertex group but im not sure how to point to the problem vertexes.
