Strange dForce simulation (extreme wrinkle)

Hello!
I would like to ask what might be going wrong with my dForce simulation.
Does anybody see a problem with my mesh?
It's hard to describe, therefore I uploaded a video here:
Thank you very much for the help!

Something to do with the vertex winding order?
Material seems too heavy and it is contouring around her bottom... Try adding underwear that might "fill the crack", or a morph to do the same thing, without harming the shape of her bottom.
Not sure if you can edit it, but if it is possible, you can set that portion of material to be "less flexible", so it retains the softer "non-folded" form, then begins to drape more after the crest of her bottom. I am not sure what they call the weighting options in d-force. The one related to elasticity and material density. Flexible material with less density (toilet-paper or silks), tends to fold and crease to contours when pulled by a larger force below. (The dress-length/weight.) However, rigid non-flexible material (felt or denim), tends to have softer distortions and contouring around creases like that.
If that were a dress, that is exactly the way it would shape around a big bottom that has no underwear on. Wearing non-spandex underwear, that is stretched across a rump, will be acting as a gap-filler.
Also, the un-natural pose of the model, bottom poking back and chest poking out, can also make it difficult to simulate reality, unless you post them in an actual natural position. Humans don't stand in the base position that the models are posed in, they are in kind-of a "vogue" pose, which is completely unbalanced and unrealistic. Hard to work around that, because most people will be using that pose, or a similar one.
All these models would fall-over, if left in the poses they are in, by default.
More natural... Shoulders down, chest tilted slightly down and back, bottom more forward, belly more out, legs with a slight kink in the knee, elbows back slightly. Poof, instant realistic center of gravity, of a human standing, unposed. :) Unfortunately, the model gets some wonky deformations in that human pose.
It almost looks like you have some geometry hidden or removed from the wearing figure? Dforce can only collide/drape properly if there is geometry underneath for the garment to collide with. Also, the skirt looks kind of lumpy and wrinkled even before dForcing, dForce cannot remove those lumps and bumps entirely so your garment needs to be smoother to start with. Hope this helps!
