karen13, yeah, I have to admit that I'm still a bit confused by all the torso-related terminology. I suspect that what it boils down to is just that my torso is so short overall that I have a very narrow sweet spot when it comes to pant rises.
La Ped and JenniNZ, I am SO glad this discussion (and my weird little "neutral glue" phrase) was useful to you! Thank you both so much for letting me know.
I suspect that for a lot of us, it's difficult to keep hold of the difference between "essentials" as the term is meant to be defined in this context and "items that are essential to expressing our style."
