I recently created a conforming skirt
i would like to know how to fix the problem I'm having
when i move the figure's leg I get this

What am I not doing ????? 

Figure in T Pose

Figure Leg Bent

Strongly suggest that you consider making the skirt dynamic cloth for use the cloth room. You can create a conforming skirt, there are many little tricks that you can use to help it move more naturally but the cloth room will give you much better results much quicker.

I usually do dynamic clothing most of the time
thought I'd giv conforming a go ....

OK no problem.

For conforming, suggest that you adjust the spherical blend zones to give a smoother transition in the central area. 

Or?
If you have PP2012 or PP2014, you can Weightmap the skirt (in twist, side-side- and bend). => You have to all 3.
That would solve al your problems.

Oh, and for an issue like this? Show the wireframe, but we see what's happening.

I think i tried that and nothing was happening
I mustve did it wrong
I'll try again 

I should've said I'm using Poser9

You can't create weight maps in Poser 9, but if your figure is weight mapped, it will transfer over if you use their rig as a donor.

The zones will still have to be adjusted. What is happening here is that the skirt now has the hip and thigh bones, so it is behaving like it does.

PhilC's suggestion should fix it.

Dynamic ;)
