What is a "geoshell underskirt" and why?

Every day that I use Daz I discover that I am a miserable n00b in some new challenging way.

The latest is in looking for products to fulfill certain needs, and finding arcane statements like this, from the product dForce Fun of the Fifties for Genesis 8 Female(s):

"Comes with lots of fabulous fun prints and color combinations that can be applied to the dress with or without the optional geoshell underskirt."

"Geoshell underskirt"? (Sigh) What is it? Why would I want to be "with or without" it? How does it work with dForce? If I go "with it," do I have to "dForce" it separately from the dress itself? Do I have to apply one of the "fabulous fun prints and color combinations" to it separately from the dress?

    That's a good question. There certainly isn't any description or explanation of how to use it or when to use it. There is no promo image showing with and without. Or if there is, it isn't annotated to explain which is which.

    A Geometry Shell is a variation on an instance - it's a live copy of the original mesh but it can be expanded/contracted with a push modifier and can have different materials applied. In this case, I think, it is being used with only the skirt cvisible and offset inwards to make an underskirt that exactly follows the shape of the outer layer. In general that should work well, but I can see situations where it may be a problem (essentially if the skirt folds over then the shrinkage might cause the inner skirt to pass through the outer).

    Well, I think the attached image shows "with" and "without" (there's no way to know, actually), but the only difference I can see is that little "slip is showing" white strip at the bottom hem of the skirt.

    Is that it? (Incredulous face here) If so, why create a "geoshell" to complicate matters—especially with dForce? Why not just have a separate materials zone on the dress that can be shown or hidden? I hope somebody who has or understands this can weigh in.

    Wow.

    In poser when using the Poser cloth room you sometimes have a dress with an underskirt which is there to actually work as a stiff petticoat, so you can make the skirt collide against  the underskirt  in a bouffant fashion,

    could a geo shell underskirt do something similar?

    No, that would require an extra item
