Bethany's G3F Corset Dress and Pose Drapes

So, this is mostly out of curiosity, since I wound up using a dress where I could figure out what it was supposed to be doing.

The question is about this dress, which came with Bethany's bundles: https://www.daz3d.com/corset-dress-outfit-for-genesis-3-female-s

As you can see from the product page, it has a bunch of "Pose Drape" sliders. Now, pose drapes are generally constructed to match specific poses or positions. When pose drapes are done to match positions that aren't in any pose set, they normally say strange things like, "Pose drape, sitting" or "Pose drape, standing 1" or "Pose drape, the Angelina Jolie Leg Thrust" or some such.

The pose drape sliders for the Corset Dress clearly feel that conveying such information would be beneath them, so they don't..

Normally, when pose drapes are constructed to match specific pose sets, they will say what sets it matches on the product page.

The Corset Dress does not. The Corset Dress clearly feels that talking about itself in such ways would be much too common.

Normally -- or at least with some frequency -- the pose drapes will be bunched into a section under the dress with a section name that matches the pose set that the drapes are supposed to match.

Does the Corset Dress do this? It does not.

I tried matching the pose drapes to the Basic Poses and the pose sets that came with Bethany. Does the Corset Dress work with those poses? No. No it does not. Clearly, it would NEVER!

So the question before the court is: has anyone who has this dress figured out what the heck those drape morphs are supposed to work with? If there's actually a set of poses out there that they match? Inquiring minds would like to know! (And would also like Daz to put the information on the product page, although that's unlikely at this very late date. Still, given that the dress came as part of a character's bundles, a single line that says nothing more than "Corset Dress Outfit for Genesis 3 Female(s)" is kind of unnecessarily terse.)

Anyway, just idly wondering if anyone out there had a clue.
