Unweighted vertices

[lolliepaws]

I'm trying to make a dress with unfitted skirt for Toddleedoo body.  I need to delete bottom vertex groups after export dress as avastar.dae. When i delete those, i get error called Please fix 596 Unweighted vertices on dress. I know there're unweighted vertices on my skirt but i shouldnt paint bottom part because i want a unrigged skirt of dress. Can anyone tell me how can i fix it without paint vertices?

You will have to provide a weight I'm afraid, all vertices in a rigged mesh must have a non-zero weight, the error message is intentional.
